Earth Day!

I recently attended an Earth Day event at the Crocodile Lake National Wildlife Refuge on north Key Largo. A group of about 20 volunteers including members of FAVOR (Friends And Volunteers Of Refuges) and local state park and wildlife refuge staff and volunteers, came out to plant native trees. We were at an overgrown, cold-war era Nike Missile Site that the tropical hardwood hammock is reclaiming. Due to the sensitive environment, this area is off-limits to the public unless there is a special project. The Wildlife Refuge was originally created to protect the federally endangered American crocodile but there are several other endangered species that fall under the protection of this "umbrella" species.

We planted over 90 Torchwood (Amyris elemifera; Rutaceae) trees which are the host plant for the federally endangered Schaus swallowtail butterfly (Heraclides aristodemus ponceanus). The Bahamian and Giant swallowtail butterflies also lay eggs on this plant. The caterpillars of all three species feed on the young leaves of torchwood. Besides being important for insects, this tree provides interesting and important uses for humans, as well. Torchwood is in the citrus family and has edible fruit and some medicinal oils. The common name comes from its use as a torch; the young green branches are full of volatile oils which are easy to ignite.

The native plant nursery for Dagny Johnson Botanical State Park grew the plants from seed and nurtured them along for several months. Apparently, torchwood is very difficult to grow from seed and many of the seedlings did not make it; we were lucky to have as many as we did. The soil in the planting area was coral limestone rock with little topsoil. Torchwood likes to grow on open edges so holes were dug along the edge of a dirt access road, out in the full sun. The native soil in the planting holes was mixed with a small amount of potting soil and a few fertilizer pellets to give the seedlings a fighting chance in this harsh environment. At least three inches of mulch in a three foot diameter was laid down around the seedlings and two gallons of water were given to each plant to help them establish. Refuge staff will continue watering the plants periodically. 

Many of our local butterfly experts who perform annual surveys for the Schaus swallowtail joined the group. Historically, the Schaus swallowtail butterfly was found throughout the southern tip of Florida in Dade and Monroe counties, extending south to lower Matecumbe Key. Now its range is restricted to several small islands in Biscayne National Park and north Key Largo, with less than 100 butterflies counted per year during annual surveys. Scientists were worried that the Key Largo population had blinked out, after not seeing any butterflies for several years in a row. Luckily, two Schaus swallowtails were observed flying on Key Largo last spring
. One individual male butterfly was observed flitting around volunteers' heads for over 10 minutes! Even though he was observed "on the wing" they were able to take several hundred photos and got a clear shot for a positive ID. In June 2014, several hundred hand-reared Schaus swallowtail butterfly larvae and a few adults and pupae were released on nearby Elliott Key in Biscayne National Park, we are hoping that some will end up flying down here and re-populating the hammocks on Key Largo. Hopefully our torchwood trees will thrive and become a flaming beacon to the Schaus swallowtail butterflies.

A Perspective on Preservation

Preservation versus Conservation versus Restoration, what do all these terms really mean and where did they come from? The history of these ecological terms in the United States has roots in Manifest Destiny, the European settlers’ westward expansion through the country. The early advocates of what is now considered the ‘conservation ethic’ were John Muir, Teddy Roosevelt, Gifford Pinchot, Aldo Leopold, Rosalie Edge, Henry David Thoreau, and Rachel Carson. Although they were all committed to the environment, several of these visionaries had clashing opinions on how to protect natural resources ranging from complete preservation with no more human interaction than hiking and camping to conservation of natural resources for managed use of timber, fisheries, mining, and other resource extraction. The most famous of these battles was between John Muir and Gifford Pinchot over the damming of the Hetch Hetchy Valley in Yosemite National Park to make a reservoir for the growing city of San Francisco. John Muir died soon after he lost this battle and the bitter taste of losing Hetch Hetchy lingers in the memories of many Californian conservationists. But I digress... The short story is: preservation equals very limited human use, think National Parks and Wilderness Areas; conservation equals human resource use, think National Forests and certain Marine Sanctuaries; and restoration equals any degraded area that we want to bring back to a more natural system.
Our first National Park was Yellowstone, created in 1872 to protect the unique geological features found there. It was also the first national park in the world, setting the precedent for environmental action for the world to follow. Photo by Yellowstone NPS, Flickr Creative Commons.
Although we may be able to restore natural areas to a semblance of what they once were (see my last blog), there is no way to fully replicate what was lost. The only way we can be certain we are protecting the majority of species within an area is by protecting the entire area and limiting resource use to light recreational activities. (This is not always possible, especially in developing countries, but that is another blog.) Scientists agree that no place on earth is untouched by humans; either prehistoric humans or current changes in climate leave no stone unturned, so to speak. However, there remain many habitats all over the world with unique life that need to be protected before they are destroyed by our quest for resources. Ecosystems provide humans with valuable services like water production and filtration. Plants especially, provide us with CO2 sequestration, O2 production, and air filtration. By protecting and preserving natural areas, we only help protect and preserve our human health into the future.

The complexity of the natural networks and webs within ecosystems are so elaborate that we do not even understand them yet. For instance, in just the last 10-15 years we have discovered that plants’ roots are networked underground via specialized mycorrhizal fungi that connect to the roots with their hyphae, the branching filaments that make up the fungal mycelium. Plants may share or steal resources, alert each other to insect pests and threats, and undoubtedly, more exciting discoveries will be made as research is on-going into the complexity of this fungal internet. Once a forest is clear-cut however, how do we replace that network? How do we replace species that we do not even know exist yet?

In arid and semi-arid habitats there are cryptogamic crusts otherwise known as biological soil crusts that cover areas of ground between vegetation and are composed of mosses, lichen, fungi, algae, and cyanobacteria. This “endangered soil” is highly susceptible to trampling disturbance by humans (that’s right hikers! watch where you walk), livestock, and off-road vehicles. Some of these crusts may recover from trampling in up to a mere 20 years, but others may take hundreds of years to reform. Biological soil crusts are important for retaining soil moisture, providing nutrients to the soil, and helping with seed germination. Desert plants need all the help they can get with such low rainfall (<10 inches/year) and these biological soil crusts play an important role in water retention in this ecosystem. I myself have inadvertently trampled delicate areas of soil crusts while out botanizing in the California deserts; I winced with each step as I heard the soft crunch underfoot. This gave me new meaning to the familiar quote by Chief Seattle, “Take only memories, leave only footprints” as I did not want to leave even a footprint. We think of deserts being full of loose sand, like Lawrence of Arabia crossing the dunes, but many arid regions have compact soils with little or no water-holding potential. Once we develop these areas for suburban sprawl, military activities, and even parks for hiking, there is very little we can do to restore the biological crusts and the limited plant life may not be able to reproduce due to unsuccessful seed germination.

On the flip side, consider the rainforests of the Northwest Pacific coast. The Pacific temperate rain forest ecoregion is characterized by high rainfall of up to 120 inches/year and moderate temperatures averaging between 50-70℉. In Oregon and Washington, less than 10% of the original old-growth Douglas-fir forest remains. These coniferous forests, including the coastal redwood forests of northern California and southern Oregon, are relicts from 5 million years ago when conifers covered much more of the Earth during a cooler ice age. What little we have left, only about 4% of which is old-growth redwood forest, requires serious protection. With climate change and global warming, these forests are already at risk of extinction and with added logging pressure, these magnificent old-growth stands are certainly doomed unless they are within park boundaries. Luckily, Redwood National and State Parks protects 45% of that remaining 4% of coastal redwood forest for us and the creatures that live there. How do we replace trees that may live up to 2000 years? Haven’t we cut enough down already or do we really need to hit the 100% mark?

Humans have an innate affinity for nature. We are genetically programmed to feel comfortable in a savanna setting, the type of habitat where we evolved into modern humans. The first time I experienced a true savanna and prairie was on Walpole Island nestled between Michigan and Ontario at the mouth of the St. Clair River. The indigenous 1st People, a blend of Ojibway, Pottawatomi, and Ottawa tribes, have always lived on the island, never ceding it over to the Canadian government. Because of this, Walpole Island has the largest existing prairie and savanna ecosystem left in the Great Lakes. I never thought I would see these habitats despite my attempts to seek them out in little slivers along railroad lines and at the edges of graveyards. Most of the great prairies were turned into agricultural fields long ago and the remnants that remain are difficult to manage since they need to be burned periodically. The Walpole Island prairies and savannas have been actively managed with fire by tribal members for as long as their history exists, which is centuries before the introduction of the European settler. There are hundreds of species of plants that occur nowhere else and I could not believe my eyes as I stood in the middle of their majestic tallgrass prairie. A photo does not do it justice, one must experience the grassland, as is the case with most awe-inspiring events. Maybe it was my genetic programming that kicked in or simply the beauty of the grassland, but it certainly was a very moving moment that brought tears to my eyes. I wanted everyone to have an experience like that in nature as we all need it on a fundamental level.

Places like Walpole Island do not exist in our reality anymore. Unless they are protected and shared by governmental organizations or we are fortunate enough to live or work in a park, nature has been largely removed from our lives in the Western world. Having public parks with open access for non-impact recreational activities is important to keeping us human. And I don’t just mean large national parks or biosphere reserves, but on a smaller scale, state & county parks are effective ways to preserve habitats and afford direct access from nearby communities. Indeed, in Miami-Dade county there is a program called Connect-to-Protect which is tasked with connecting the remaining pine rockland habitats within the county through private landowners’ properties. By planting native pine rockland species, homeowners can facilitate gene flow between plant populations by encouraging insect pollinators and connecting the remnant pine rocklands on a regional level. This extremely threatened habitat was once found along the rock ridge from northern Miami Beach south and west into Everglades National Park. Just 2% of this habitat remains outside of the national park and numerous endangered species of plants and animals are hanging on by a thread. By preserving what remains and educating the public on its importance, there is hope that this endangered habitat and its inhabitants will grow and flourish once again.

We need to preserve what is left not only for our sanity but for our children and future generations to enjoy and learn from. Most importantly, we are the voices for plants and animals who cannot save themselves from our civilization. We are all connected and as different parts of our ecosystems break down, they become more and more fragile, breaking our society down with them. When we are cooped up in cities with no outlet to natural spaces, we lose touch with the Earth and where we come from, we lose the desire to protect natural areas since we have lost our connection with the outdoors, and we become grumpier and less happy. Nature-deficit disorder has been coined has the phrase to describe modern children (or people in general) who are growing up without unstructured play in the outdoors, and their propensity towards depression and obesity. Education is the key and the outdoor classroom is the best place to learn. No one is too old to learn how important and useful plants are, how fascinating insects can be, and how interesting birds are. We are naturally happier when outdoors, as long as predators are not lurking in the underbrush!

Reclaim and Restore

Our human footprints are found all over the world, in every habitat on each and every continent. Areas that we consider truly wild have the faintest imprint of humans on them, but there is no where on this planet that is untouched and pristine. We are everywhere because we are part of nature and have successfully spread around the world colonizing every habitat. Now, in order to escape our built environment that seems so far removed from nature, it seems we must travel long distances to seek out solitude.

Mt. Banner and Thousand Island Lake in the Ansel Adams Wilderness Area - Inyo National Forest, California
Wilderness is an area that we crown with this title. According to The Wilderness Society, ‘Wilderness is a type of protection given to the most pristine wildlands - areas within national parks, forests, recreation areas and other wildlands where there are no roads or development”. Webster’s Dictionary defines wilderness as, “a wild and natural area in which few people live”; but there are still people, if even only a few. In order to obtain a sense of wilderness and peace in nature, to maintain habitat for other species to coexist with us, we must now restore areas we have degraded through human industrial activities. In order to protect our urban habitats from storms, which are becoming fiercer and more frequent, we must build our environment as close to a natural system as possible so that it will withstand the strong winds and waves that come with each passing storm and help protect our homes and businesses from damage.

Restoration is the act of returning something to its original condition by repairing it. This can happen naturally in areas that are adjacent to intact, undegraded habitat where there are plants nearby to supply seeds for regrowth. Over time, seeds will drift in or be carried in by animals allowing plants to regain a foothold, or rather, a roothold. Terrific examples of this abound: Pripyat, the town near Chernobyl, and areas of cities like Detroit where after decades of being abandoned, plants and trees have sprung up through the old buildings and factories to reclaim the land; and right here in North Key Largo, where the land was scraped and leveled for agriculture then cleared for housing developments that were never built and has now returned to hardwood hammock, complete with several endangered species that are under Federal and State protection.

An endangered Key Largo Woodrat (Neotoma floridana smalli) nest in the base of the trees' roots. This area was likely a key lime orchard in the 1940s and has naturally returned to hardwood hammock over the years. Due to the alteration of the topography, land managers must now create artificial nests for the woodrats. This nest was created by power washing the bases of the trees to create an underground living quarter.
Plants are highly adaptable, especially here in a hurricane zone. Coastal plants around the world in subtropical to tropical latitudes have evolved with tropical cyclones (hurricanes are one type of cyclone) and all the chaos that comes with them: pounding rain, high winds and flooding from storm surges. Right here in our Gardens, a native Sea-grape tree (Coccoloba uvifera) at the beach was blown over and nearly uprooted by Hurricane Wilma in 2005 but has resprouted and is a stunning shrub. We also have a stubborn little fire bush (Hamelia patens) in our parking area that has made a coral rock its home for a quarter of a century! Designing our future shorelines and barrier islands for storm protection really hit home after Hurricanes Katrina in 2005 and most recently Sandy in 2012. Many municipalities are looking to innovative green building designs coupled with restoring marshes and beaches with locally adapted native plants for their resilience and tenacity in the face of these storms.

Restoration can also be facilitated by us, think of gardening on a landscape level with bulldozers recontouring the land and native plants repopulating the landscape. Seeds are collected and either grown out in a nursery or directly seeded across the landscape to reintroduce the local native flora back onto the site. This type of restoration must be done when the degree of disturbance is high, such as with mining operations and other large-scale land disturbances like landslides and hurricanes. It may also be useful in brownfields and abandoned agricultural areas. 

Genesee Coal Mine & Power Plant in Alberta, Canada- Reclamation projects have been in place since 1990, returning mined lands to agricultural use and wildlife habitat. 
The largest restoration project east of the Mississippi River is in North Florida on the 51,000-acre Nokuse Plantation. This formerly neglected land is being turned back into longleaf pine forest (Pinus palustris), of which only 3% remains in the southeast United States. By repairing our damaged landscapes, we may bring a bit of wilderness back into our lives, right in our own backyards and cities. Wilderness does not need to be an out-of-the-way, untouchable resource that only a few hardy individuals can make the trek to experience.

If we are fortunate enough to live near a national park or forest, a wild and scenic river, a state or county park, or even undeveloped land, we can experience that sense of wonder and place in nature. These parks may also provide an outlet for volunteering on restoration projects. For several years I worked in the Presidio of San Francisco where they have a community-supported restoration program. The Presidio is a former military post and over the last 2 decades it has been managed for restoration of its natural areas, to minimize landfills deposited by the U.S. Army and to help preserve its habitats for rare plants, insects, birds, and mammals. The convenience of the park being within the city limits of San Francisco encourages many citizens to come out and lend a hand in restoration activities. After heavy equipment hauls out the remains of landfills and recontours the slopes of the sand dunes and bluffs, crews of volunteers and school groups come out to assist with the restoration efforts. Needless to say, parts of the park have been transformed back into wilderness areas with coyote and gray fox prowling amongst the rare wildflowers on the dunes once again. If you plant it, they will come!

Our wildlife ecologist managed to snap a picture of a rare sighting of a grey fox! The last record of a grey fox sighting in the Presidio was in 2004. The fox scrambled onto some branches along with a raven as a coyote prowled around a bush below. Thanks to Jon Young for the incredible picture! (Feb. 2015)
No matter where you live, you can rewild your yard by planting native plants or becoming involved with an organization in your community that is restoring a local natural area. Being out in nature is beneficial to our spirit and mind and experiencing a restoration project adds an extra layer of care for the earth; we become personally invested in our natural areas. It is a great way to learn the local flora and fauna and connect with other community members. We can all contribute to creating wilderness a little closer to home. As David Byrne said in his 1988 hit (Nothing But) Flowers, "Once there were parking lots, now it's a peaceful oasis".

Spring-Cleaning in the Nursery

While we do not exactly have a spring season in south Florida, I use the common phrase “spring-cleaning” to denote this particular activity. I initiated an effort to clean out some of the weedy and invasive species that we have growing in our nursery and shade house. We have very limited nursery space to grow seedlings, cuttings and pups from some of our collections, therefore space is at a premium. Last month we obtained new plant specimens from nearby Fairchild Tropical Botanic Garden and last week we received several new arrivals from Montgomery Botanical Center. While we finalize garden planning on where to place these specimens, they may wait in the nursery area for several weeks before being out-planted. By cleaning out the nursery and taking stock of what we have, we can make space for new arrivals, focus on keeping plants healthy, and most importantly, remove invasive species.

I realized that we had several plants that are considered invasive species in south Florida and the Keys, while doing an inventory of our nursery stock. This issue is important to me since I have worked on the land management side of botany and seen what havoc invasive species can wreck on the environment, not to mention the hours spent removing the pests and the amount of tax-payer dollars spent trying, in vain, to control these weeds. While oftentimes these plants are beautiful, if they make it out of gardens and into our natural areas, they become invasive and threaten our native, south Florida species, many of which are already rare. Our Gardens are about 0.5 miles from the nearest natural area to which birds could potentially spread seeds. By having these plant species in our Gardens, visitors may be inspired by their beauty and possibly plant them at their homes, spreading the problem further afield. I would like to inspire people to plant native plants and non-invasive exotic plants. By eliminating the potentially invasive species from our Gardens, we can rest assured.

Among the plants we have removed from our nursery so far are wart fern (Microsorum scolopendrium) and Asian sword fern (Nephrolepis brownii), tropical almond tree (Terminalia catappa), Mexican fan palm (Washingtonia robusta), and cardboard palm (Zamia furfuracea – a cycad). We have begun removing fountain and napier grasses (Pennisetum setaceum/ P. purpureum) from our landscape and are replacing them with native grasses. There are a few specimens of other invasive exotics in the Gardens that we are grappling with: strawberry tree in our fruit garden (Muntingia calabura), arrowhead vine (Syngonium angustatum) climbing up a palm trunk, Governor’s plum (Flacourtia indica) & Brazilian pepper (Schinus terebinthifolius) providing privacy along a property line and actually rooted on the adjacent property, and foundation plantings of Queensland umbrella tree (Schefflera actinophylla) that provide shade and block road noise for guests and have been on the property for over 20 years.
Removing plants from the nursery is one thing, but how do we deal with these mature plants in the ground? To remove a Schefflera is a huge task with a high price tag, and with nothing large enough to fill its place, would leave a gaping hole. When is having a specimen that you can educate the public with more beneficial than removing it? These are some of the tough decisions that botanic gardens must make when potentially invasive species are part of our collections.

Cardboard palm (Zamia furfuracea) ready to be composted. This species has been added to the Florida Keys list of invasive plants due to its tendency to spread from the landscape into natural areas by seed dispersal. It pops up all over our Gardens from existing plantings which we are working on replacing.
A Tropical almond (Terminalia catappa) sapling on its way out. Seedlings of this species pop up throughout the Gardens even though the mature tree was cut down years ago. New seeds may arrive in mulch deliveries, as well.

Wart fern (Microsorum scolopendrium) that has escaped its nursery pot and started to grow along the ground. Watchful botanists in Miami Dade county are adding this plant to the state invasive species list as it is showing up in natural areas. It is not yet invasive in the Keys, and in fact may not become invasive down here since we have a drier climate, but we have many visitors from the metro Miami area and do not want to encourage them to plant this fern.

Asian sword fern (Nephrolepis brownii) specimen. This species is listed as invasive for Central and South Florida and is invading hammocks in the FL Keys. It is also invading nearby pots in the orchid house (see photo below). Ferns can be particularly tricky due to the multitude of spores they release. The Old World climbing fern and Japanese climbing fern (Lygodium microphyllum, L. japonicum) are both major problems in Florida and in several other southeastern states. Since its introduction in the 1960s, Old World climbing fern now covers 50,000 acres of habitat in Florida, literally climbing over every other plant in its path.  

Small sporophyte of Asian sword fern growing in adjacent pots.

On the flip side, botanic gardens may be some of the first places that a new species’ invasive potential becomes known, or a new pest becomes evident. It is then our obligation to spread the word and inform the local extension service and regulatory committees of the threat. Having staff members that are part of a local invasive plant watch group is helpful to stay abreast of developing issues in your surrounding area. It is our duty as botanical gardens to educate the public about these issues and promote the sale and use of local native plants and non-invasive exotic plants.

In the Florida Keys, our local eradication network is called the Florida Keys Invasive Exotics Task Force. This group includes local, state, and federal agencies and non-profit and public utility personnel who are responsible for removing invasive plants from local natural areas like state and county parks. By working with this group and others like it in south Florida (Everglades Cooperative Invasive Species Management Area & Florida Exotic Pest Plant Council) I am able to stay informed and help prevent the spread of invasive exotic species. Publications such as the AlterNatives Plant Guide are a great way to share local knowledge on landscaping and gardening with the public.

Grateful Guests and TYUP Attendees to Finish 2014

Small spaces are the rage these days. It seems that every gardening and architecture magazine has featured innovative ways to design and be comfortable in small spaces; from using raised beds and vertical gardening techniques to repurposing items like shipping containers into homes. Stores like IKEA have made huge headway into American markets and while promoting our seemingly endless desire for goods, have also shown us ways to do more with less, capitalizing on this European tradition.

And that is exactly what we do here at the Botanic Gardens at Kona Kai Resort!

When I first visited the Gardens last spring, I was very curious how they were laid out on less than 2 acres of property. Coming from a larger botanical garden (at the time I was fresh out of 83 acre Fairchild Tropical Botanic Garden in Coral Gables) I was used to sprawling grounds and long rambles between the collections looking for plants. There is even a tram tour to give visitors an overview of the entire property! While that garden is extensive and beautiful, our Gardens are also beautiful, packed with variety and easy to navigate during our botanist-led TYUP* tour.

During Christmas week, I had a family of 10 book my TYUP and they were delighted at how many plants we have in our Gardens. The patriarch of the family, a long-time volunteer at Fairchild, commented that our collections were very easy to see during the tour and that some of our plants, our cycads in particular, looked very healthy and happy. I was shining with pride! What a great compliment to end the year with.

We do our best to have a good diversity of plants with the limited space we have to work with – remember we are part of a resort and the buildings take up real estate. However, we have managed to collect over 360 plant species, cultivars and hybrids including 25 edible tropical fruits, over 20 Florida Keys natives, 38 species of palms, and 15 bamboo specimens. Not bad for less than 2 acres! We are busy adding more this year so come down to visit and see for yourself how we maximize our space.
