In this series, I will cover a variety of topics related to the wildlife of the CREW Project. While the main focus and priority is always water for people, it is also a special place where our wildlife benefit from the water and space provided, too. Second in this series – the Endangered Species Act of 1973 (ESA).

The ESA was signed into law by President Nixon in 1972. This link is just under 9 minutes created by the United States Fish and Wildlife Service (USFWS) to explain the basics of the ESA and how it works to keep wildlife – both terrestrial and aquatic – from going extinct. Video link: https://www.fws.gov/endangered/laws-policies/

Wildlife is protected because each animal is a key ingredient in the ecosystem where it lives. Functioning ecosystems are kept in check by negative feedback – there are checks and balances that keep all its components at optimal function. Losing a species may create a negative effect that ripples through an ecosystem permanently altering all other wildlife, plants, and even water – how it moves and its quality and quantity. Check out some success stories here: https://www.reconnectwithnature.org/news-events/big-features/survival-stories-animals-back-brink-will-county

This is why it is important to have the state wildlife agency, the Florida Fish and Wildlife Conservation Commission (FWC) as a partner of CREW implementing federal and state regulations (and protection once wildlife is no longer federally listed like the American alligator) through biological work and law enforcement provided by the FWC. A few of the federally listed species within the CREW Project are: Florida Panther, Eastern Indigo Snake and the Florida Bonneted Bat. In addition to federally listed species, each state lists their own protected species. State of Florida listed species found at CREW include: Big Cypress Fox Squirrel, Everglades Mink, Florida Pine Snake and Gopher Tortoise. There is wildlife that gets more attention than others so you may not have heard about some of these protected species. 

We call the attention getters “charismatic megafauna”. One of the CREW Project’s charismatic megafauna is the Florida Panther. Although the Florida panther gets a lot of attention, protecting land serves not only them, but all the animals using the same habitat. While the CREW Project’s primary goal is water for people, wildlife benefits from the water resources and the 60,000 acres of protected land. You can support our partner’s work through purchase of speciality license plates, hunting and fishing license purchases, and donations to the Fish and Wildlife Foundation of Florida that provides grants for FWC biologists. You can support the CREW Trust with memberships and donations.

Trees – why do we love them?

Written by Nan Mattingly

          In the 60,000-acre Corkscrew Regional Ecosystem Watershed (CREW) Project, you’ll find a wide variety of trees. The stars of the show are bald cypresses that dominate Bird Rookery Swamp and slash pines found throughout the CREW Project, as well as red maples that provide vivid color to the predominantly green and brown landscape. Of course, you’ll also see many sabal (or cabbage) palms, our state tree. All of the trees in CREW help filter and protect the water that soaks into the aquifer that spans Lee and Collier counties. This aquifer stores the water that we need for just about every aspect of life in southwest Florida.

          Aside from their contribution to our vital water supply, trees in the CREW Project also provide a myriad of less visible services that enrich and improve our environment. Some of those services are:

  • Natural air conditioning: when you walk under a canopy of mature trees (which you’ll find in all four CREW trail systems) you immediately notice a drop in temperature, as much as six to eight degrees. That’s a real gift in the summer months. (Trees strategically planted to shade your house can lower your electric bill by as much as 15 %.)
  • Habitat for wildlife: bird watchers can delight in the variety of birds on show among the trees, from colorful songbirds to impressive raptors (hawks, vultures, crested caracaras, etc.) to charming wading birds such as great blue herons, ibises, and egrets. CREW lands also attract fascinating seasonal visitors such as swallow-tailed kites and wood storks. Florida panthers, bears, bobcats and others rely on heavily forested areas for concealment of their dens and for hunting grounds. And if you see a mature tree that is missing a long chunk of its bark, bears may have been using that tree to scratch their backs.        
  • Capture and storage of carbon dioxide emissions: trees are the most efficient carbon capture machines in the world. Through photosynthesis, trees absorb carbon dioxide and store it in their leaves, stems and roots. That carbon provides some of the energy that trees need to grow and leaf out. Carbon dioxide traps heat in the environment, so the trees in CREW can help lower the temperature in surrounding areas. According to the Environmental Protection Agency, all the vegetation in the U.S. (especially trees) absorbed 11 % of carbon emissions in 2017.         
  • Rich, refreshing environment for hikers: CREW offers four trail systems, all of which feature some trails that are lined and shaded by mature trees. When you’ve hiked deep into the woods, the lush, cool and green atmosphere created by trees is more invigorating than a session at the gym and more reassuring than a session with a therapist.

          All of these practical reasons for appreciating trees are sensible and important. But it may be the natural grace and beauty of trees that most attracts us to them.

At Home with the Florida Duck

Volunteer Perspective Series

Written by Nan Mattingly

How Florida mottled ducklings helped this CREW Trust volunteer survive quarantine.

Before the governor of Florida imposed a safer-at-home order, I had been experiencing flu symptoms and decided to self-quarantine. So I’ve been pretty isolated since early March.

Fortunately my house is situated on the edge of a fairly large lake, so I’ve long been in the habit of watching activity on the lake. Herons of all types come here to work the banks for small fish; anhingas dive for fish, which are plentiful, and then alight on the banks to dry out their feathers; occasionally I see an osprey snatch up a fish and run; and from time to time I watch long-time resident Wally Gator make his stately way up and down the lake. And of course we have the requisite Muscovy duck population, begging at doors for bread and showing off their unique brand of ugliness. 

Right about the time I decided to voluntarily quarantine and cope with what felt like murderous viral symptoms, a miracle occurred: a pair of Florida mottled ducks emerged on my lake with a brood of ten tiny ducklings, just little balls of downy feathers. Though their nest wasn’t very near my house, the whole group took to hanging around my neighbor’s house and mine. Before they showed up, I had only a casual interest in ducks (and a decided dislike for Muscovys). Virus fatigue and a lack of other distractions, I guess, allowed me to become fascinated with the mottled family. Now, about two months after their debut, the ducklings are still a mob of ten and the parents are nowhere to be seen. How they evaded predators is a mystery. Over time I’ve had the privilege of watching them grow, develop their voices, and learn to fly. At the end of May, they’re still there, and behaving like adolescents – chasing each other around, pecking each other on the head and occasionally making test flights across the lake.

Once the little ducklings had attracted my feeble attention, I developed the habit of looking out at the lake first thing every morning to check on them. They tended to arrive in my backyard around 6:30 a.m. Until a few weeks ago, they made tiny little peeping noises, which were charming, but unfortunately they are now developing that distinctive duck voice. On Memorial Day I was awakened early by a chorus of quacking before they did a very patriotic flyover of my lanai.   

Anticipating the sad day that my ducklings depart for bigger things, I checked the FWC website to learn when I can expect to become an empty-nester. It was mostly good news. First, I learned that we in south Florida have the pleasure of hosting these ducks year-round; they tend to live south of Tampa and are non-migratory. They are a member of what is called “the mallard complex” which includes about 20 species of ducks, all alike in body shape but distinguished by their feather characteristics and colors. FWC noted that the Florida mottled duck is also known as the “Florida duck” or the “Florida mallard” because they are found only in Florida.  

Some people might find a mottled duck’s grey and brown coloring a little boring compared to the mallard, which I now consider to be the designer version of mottled ducks. The mallard has that showy display of teal bordered with white on their wings. Mottled ducks, male and female, have a more subtle version of that coloring on the wings with almost no white showing.  

There’s little difference in coloring between male and female mottled ducks, so you have to look at the bills to distinguish them. The male has an olive green-to-yellow bill while the female has an orange-to-brown bill. 

Watching the ducklings peck in the grass and dip their bills into the water, I tried to figure out what they were eating. FWC supplied the answer: about 40 percent of their diet comprises insects, snails, mollusks, crayfish and small fish. For the other 60 percent, they eat grass seeds, stems and roots, the seeds of other marsh plants, and bayberries.

I knew that my particular ducklings were special not only for their  survival skills and playful personalities, but according to FWC, a female produces only one brood a year and typically lays eight to ten eggs. The mother of my ducklings must have produced a pretty big clutch of eggs, and she must have protected them well. For the first two months or so, the parents hovered over the ducklings and shepherded them around the lake, giving them a good start in life.

It’s not all good news for the Florida mottled duck, however. Go to the FWC website and read about the challenges to the long-term survival of our unique south Florida duck. Loss of wetland habitat, of course, is a big threat. And what FWC calls “feral mallards” have been mating with mottled ducks and producing hybrid offspring. 

Having relied on my mottled ducklings to keep me distracted and happy during a tedious quarantine, I’m sorry to contemplate the threats to this special south Florida dabbling duck. We’re still looking for a cure for Covid-19. Watching ducks grow up won’t cure anyone, but it’s a great distraction. Today I’m as healthy as those ten beautiful mottled ducks, and I thank them.

North American Model of Wildlife Conservation

CREW Education Series

by Jayne Johnston, CREW Trust Education Coordinator

photo by Bill Zaino

In this series, we will cover a variety of topics related to the wildlife of the CREW Project. While the main focus and priority is always water for people, it is also a special place where our wildlife benefit from the water and space provided, too. First in this series –  how wildlife is conserved in the United States.

During the settlement of the United States, wildlife harvest was unregulated. As the country grew in size and population, overharvesting coupled with habitat loss to development and agriculture made a significant impact on wildlife populations. The decline became evident enough by the late 1800s that the 1900s ushered in a new wildlife ethic. Federal laws were passed – Migratory Bird Treaty Act of 1918, Migratory Bird Hunting and Conservation Stamp Act of 1934, Federal Aid in Wildlife Restoration Act of 1937, and Federal Aid in Sport Fish Restoration Act of 1950. These pillars of wildlife legislation were made possible by engaged citizens, just like CREW came to be through similar efforts. These laws formed the foundation of what biologists and policymakers follow as a guide to wildlife management – the North American Model of Wildlife Conservation. Here are its seven principles:

  1. Wildlife is a public resource. Wildlife is treated separately from other resources like water and land.
  2. Markets for game were eliminated. Commercial wildlife harvest decimated wildlife populations. Southwest Florida was known as the heart of the plume (feather) trade for women’s hats. Legislation and the Audubon Society put an end to the devastation of bird rookeries (bird nurseries) that could be found at the CREW Bird Rookery Swamp.
  3. Allocation of wildlife by law. Think of hunting regulation with its seasons, bag limit, and types of species allowed. The Florida Fish and Wildlife Conservation Commission (FWC) oversees these efforts at the CREW Project through onsite law enforcement and biologists. 
  4. Wildlife can only be killed for a legitimate purpose. Purposeful hunting prevents waste and needless death. 
  5. Wildlife species are considered an international resource. We are fortunate at CREW to see so many migratory birds from Canada and South America. Swallow-tailed kites arrive from South America to nest here and warblers from Canada visit CREW after their summer nesting season. The Migratory Bird Treaty Act and CITES guide how these resources are shared among the U.S., Canada, and beyond.
  6. Science is the proper tool for discharge of wildlife policy. Sound science – population counts, species research, biological inquiry –  helps governments design wildlife hunting regulations (lowest protections afforded wildlife like for deer and turkey) up to federal protections as endangered wildlife (strongest protections afforded wildlife like for Florida panthers and Eastern indigo snakes) The democracy of hunting. Access to wildlife is for all!

While we lost the Caribbean monk seal, Carolina parakeet, (yes, Florida used to have its own native seal and parakeet) and Passenger pigeon, we recovered the American alligator, White-tailed deer, and Wild turkey. We are attempting to recover the Florida panther, Crested caracara, and Gopher tortoise. The model works! You can find alligators, deer, turkey, panthers, caracara, tortoises and others at CREW. You can also help wildlife through purchases of hunting and fishing licenses (referred to as consumptive use – people consume their harvest), the abundance of specialty license plates that support wildlife recovery efforts, or by supporting our partners if not a hunter (referred to as non-consumptive use like wildlife viewing and hiking) – the South Florida Water Management District (SFWMD) and the Florida Fish and Wildlife Conservation Commission (FWC) and by supporting the CREW Trust through memberships, donations, and volunteer service.

Pop-Up Event at CREW this Saturday 5/9/2020

We miss seeing our CREW friends! 

Join us, the CREW Land & Water Trust staff at CREW Flint Pen Strand trails this Saturday, May 9th from 8-10 a.m. We can’t wait to see you so drive by to say HI or plan to take a hike and enjoy the trails. 

Brenda Brooks, our Executive Director will be in the Main parking lot (the big lot). You can catch up with Allison Vincent, our Communications Director out on the trails. If you’re into more bird watching and less hiking, be sure to head over to the Lakes Parking lot to say HI to our Education Coordinator, Jayne Johnston. Binoculars and guides will be available for you!

We will practice safe social distancing with face-cover, keeping at least 6 feet of separation at all times, and avoiding the trail “gauntlet” while hiking (see infographic above)

If you haven’t been to the newest CREW trail system here’s the address for CREW Flint Pen Strand – 15970 Bonita Beach Road, Bonita Springs, FL 34135 (left on dirt road)

See you on the CREW trails this Saturday!

All CREW Trails OPEN- April 29, 2020

You’ve all waited patiently for your favorite CREW trails to reopen. Well, the day has arrived!

You can immediately head out to the trails to enjoy the fresh air at all four CREW trail systems: Bird Rookery Swamp Trail, CREW Marsh Trails, Cypress Dome Trails and Flint Pen Strand Trails.

Please remember we all need to practice social distancing, even on the trails.

Consider the “bottleneck” areas, like the parking lot or boardwalks as spaces to be especially considerate of others space.

We will continue to update our media pages as we learn more from the South Florida Water Management District.

Sprucing Up the CREW Trails

Before the trail closure on April 4th, CREW Trust staff, volunteers, and Florida Gulf Coast University (FGCU) students were out in full force finishing up some big projects during the final cool months. 

Several projects include the Wild Coffee Trail/White Trail revitalization at the CREW Cypress Dome Trails, the installation of new green and yellow post trail markers at the CREW Cypress Dome Trails, widening the Popash Trail at the CREW Marsh Trails, and an Adopt-A-Road cleanup along Corkscrew Rd. 

Our CREW trails consistently undergo huge improvements thanks to our dedicated volunteers and students that know how to complete a project from start to finish. 

Currently, trails are closed to the public and CREW Trust volunteers, but this does not mean that the volunteers have lost their enthusiasm. They have found many creative ways to help throughout the Florida #stayathome order!

Partner Spotlight

The South Florida Water Management District (SFWMD)

SFWMD Prescribed Fire at CREW Cypress Dome Trail

You may already know the general story of the CREW Project. In 1989, a conservation minded group of go-getters banded together to protect the land that makes up the CREW Project today. What you may not know is how the land was chosen and how the South Florida Water Management District (SFWMD) emerged as the primary land owner and land manager of the CREW Project’s 60,000 acres.

In the 1980s, after several years of drought caused wells to go dry, the Lee County Board of County Commissioners applied to the state Save Our Rivers Program land acquisition program (later becoming the Conservation and Recreational Lands Program (CARL) and now known as Florida Forever), asking the state to purchase Flint Pen Strand for a water recharge area to ensure a better water supply for southern Lee County. 

At the same time, National Audubon Society’s Corkscrew Swamp Sanctuary and the Conservancy of Southwest Florida also asked the state to purchase Bird Rookery Swamp to protect the southern and western edges of the Corkscrew Swamp Sanctuary. 

The state looked at both applications and noticed that the two parcels of land were near each other. They studied the area further, discovered there was an entire undisturbed watershed system and determined that the whole system needed to be protected.

Parcel by parcel, the National Audubon Society, Lee and Collier counties, and the state began acquiring parcels within the watershed. The state turned over land management duties to the SFWMD after acquisition. The SFWMD manages their lands to support continued or improved water flow for the benefit of Lee and Collier County citizens.

It is truly a cooperative effort and the key to our success has been partners like the SFWMD. The CREW Trust thanks you!
