Strolling Science Seminar: Murder, Mutualism and Medicine

Love chocolate? Love caffeine?

If you do, then you are familiar with natural products produced by plants.

Join CREW Land & Water Trust and Dr. Maureen Bonness for an informative guided walk through Bird Rookery Swamp, located at 1295 Shady Hollow Blvd. in Naples, on Saturday, March 18 at 9 a.m.

Dr. Bonness will discuss plant natural products and how these products have profound effects in swamp ecology, including the interactions between plants and their swamp co-inhabitants. Toxins, colorants, scents, herbs and medicines are all plant natural products that humans use. While many plant products are used for their beneficial properties, some are used nefariously.

Tickets are  $15 for members and $25 for non-members; reservations are required and spaces are limited. For more information or to purchase tickets, visit eventbrite.com.

There’s more to see than alligators, bears and panthers

One of the most common questions I hear, either on the phone or on the trails, is “What will we see?” or “Which trail is best to see wildlife?”

Red-shouldered hawks at CREW Marsh Trails

The answers: Sadly, we can’t predict what you will see and, all three trails are different.

Bird Rookery Swamp is our most visited trail system, and for good reason. You can walk less than a mile and see alligators, wading birds and the occasional otter or bobcat. Sightings of alligators are almost guaranteed.

This means that, when choosing a trail system to visit, people often overlook Cypress Dome Trails or CREW Marsh Trails.

A large alligator at Cypress Dome Trails

There are alligators at the Cypress Dome Trails, but you’ve got a pretty long hike if you want to see them. At the CREW Marsh Trails, people seem to think that bears, boars, bobcats and panthers will be out there all day, just strolling by. And, if they don’t see large animals, there is disappointment, a feeling that is sometimes vocalized as “We didn’t see anything.”

 

For me, the marsh trails are my favorite. It’s the first trail system I visited, and the first trail system I worked as a volunteer. It’s the first trail system Brenda took myself and my three kids to during their Spring Break a few years ago. It’s the trail system that my youngest daughter loves to hike and my oldest loves to go trail running.

What do we see there?

Everything.

Butterflies, dragonflies, red shouldered hawks, palm warblers, eastern diamondback rattlesnakes, a giant beehive, lubber grasshoppers, wildflowers and, right now, swallow-tailed kites. And that is only a small fraction of the flora and fauna that is there.

Two of our volunteers, Jane and Laurel, recently spent a day cataloging all of the plants, birds, dragonflies and butterflies they saw at CREW Marsh Trails. It’s a great example of how much is there on the trails, so much more than bears or boars or panthers or alligators.

Swallow-tailed Kites are here!

For the last two weeks, the CREW Trust staff and FWC biologists have been anxiously watching the skies.

Why?

It’s Swallow-tailed Kite time.

Reports trickled in from our volunteers. Jayne posted on Facebook that she saw kites during a hike with students from FGCU on the Marsh Trails . Peggy sent us an email that she saw two at the observation tower at the same trails and they were “calling like crazy!”

I led a small group of volunteers through trail steward training on Sunday and kept one eye on the sky but still, no sightings.

Swallow-tailed kites come to SWFL to breed and are always spotted mid-February, right around Valentine’s Day. Sightings are not limited to our trails, but the birds do require tall trees for nesting and tend to choose open pinewoods near marshes or cypress swamps as their habitat.

In other words, CREW is great breeding spot for them.

The kites will be here until late August. If you’re eager to spot one or two, head out to Cypress Dome Trails (3980 Corkscrew Road) or CREW Marsh Trails (4600 Corkscrew Road) and keep your eyes on the skies!

 

This week’s Bird Rookery Swamp critter count

Each week volunteers Dick Brewer and Rick Mears walk the trail at Bird Rookery Swamp and complete a critter count. Below is this week’s list. This is a great example of citizen science and we hope you’ll hit the trails and see if you can match any of their findings!

Merry Christmas and Happy CREW Year

Happy Holidays from all of us at CREW!

 

Christmas is just days away and, once the wrapping paper settles and the cookies disappear, it’s time to start thinking about New Year’s Resolutions. We’ve got a few ideas for last minute holiday gifts and ways to make 2017 the best year yet.

Give the gift of guided walks

Our guided walks are free, but the knowledge of our volunteer leaders is highly valuable. Sign yourself up and head to Bird Rookery Swamp for two hours of George’s or Bobby’s stories or go out with Dr. David Cooper for a tour of CREW Marsh Trails. Better yet, sign up a friend. Guided walks are a great way to build confidence in new CREW visitors, and that confidence level increases the chances that they will return to explore more of the trails.

Share nature with kids and grandkids

The electronic hatching egg everyone is clamoring for will only engage kids for so long, and by New Year’s Day, it will be forgotten in a pile of toys. Memories last much longer, so give the gift of time and take your kids or grandkids out to your favorite trail.

The going may be slower as they stop to see every tiny flower or search for animal tracks, but it’s the memories that count, not the miles. And if they ask a question and you don’t know the answer, give them homework and tell them to google it, then get back to you with the answer.

If you are looking for a way to wrap up that idea, make a coupon for one guided hike with Nana or Uncle Todd (insert your name) and give it with a field guide or binoculars or kid-sized hiking stick. (Hint hint, we sell those at the CREW office).

They’ll talk for years about seeing one-eyed Ida and completely forget about whatever game they got for their NintendoDS.

This holiday season, hit the trails with friends and family and help us spread our mission of protecting and preserving our watershed.

Honor a loved one

While Christmas and New Year’s is a time of celebration, it can also be a time of reflection for those that have lost loved ones and friends this year.

Consider making a donation to CREW as a way to memorialize a grandparent who first introduced you to birding or always remember a sun-filled day when you spent the morning identifying butterflies with your visiting best friend.

New Year, new you

The top New Year’s resolution each year is fitness. Gym memberships surge and by mid-February, everyone is back to their old habits.

At CREW, we’ve got a great way for you to get active and stay active all year long: volunteer as a Trail Steward.

After a short training session, you’ll have a snazzy blue volunteer shirt and be ready to hit the trails, acting as an ambassador for CREW and answering questions as you stroll your favorite trail system. There are no set hours; we just ask that you wear your volunteer shirt when you go hiking, then log your volunteer hours when you get home.

You’ll not only stay committed to your resolution, but you’ll be sharing your love and passion with others while helping CREW continue our mission of protecting and preserving our watershed. It’s a gift that keeps on giving!

Bird Rookery Swamp Reopens

After several weeks of being closed to protect our natural resources, the CREW Bird Rookery Swamp has reopened to the public. Thank you for your patience.
 
Walkers, hikers, and bikers should know trail_water_0808that the 12-mile trail is flooded and muddy in several places. Due to recent rainfall and high water, parts of the trail haven’t been mowed and grasses in those parts of the trail may be high.
*For a more detailed update on trail conditions see below.
 
As usual, respect the wildlife and their young. Give them plenty of space. After all, it’s their home, we’re just visiting. Thank you.
 
*Please use caution:Water is over the trail at the end of the boardwalk (about 4” deep), just past Trail Marker (TM) #3 heading towards TM#4 (about 9” deep) and from TM #6 to TM#3 (about 20” deep). The trail is muddy near TM#2, in the mid-section of TM#4-TM#5, and between TM#6 and TM#3. 

What you should know if you visit the CREW Marsh Trails…

In a few weeks, the CREW Marsh Trails will get more exciting. Winter is the CREW Trust’s premier time for guided walks and this includes field trips of all kind. So, don’t be alarmed if you drive out to the Marsh Trails and see a group for a guided hike, 120 third graders or a class of college students.

The CREW Marsh Trails opened in 1994, and since then we have been expanding and enhancing our education programs for all ages.image018

  • Guided hikes: Dr. David Cooper will present his enjoyable and informative walk every second and fourth Tuesday and the second Saturday of each month at 9:00AM.
  • 3rd Grade Field Trips: Collier County third graders come to CREW to take a “Walk through the Watershed” where they spend time dip-netting, getting to know where their water comes from, and the importance of protecting the Corkscrew Regional Ecosystem Watershed.
  • College Field Trips:  Students take a walk through the five beautiful ecosystems that the Marsh Trails have to offer while exploring the concepts of sustainability, sense of place and interdisciplinary connections to our environment.

As part of our mission to protect the Corkscrew Regional Ecosystem Watershed, these educational IMG_0273programs are important to developing support for the watershed and engaging people in its protection.

So, the next time you go out to the CREW Marsh trails on a weekday, you might run into many people learning about the wonders of this 60,000-acre watershed. If you would like to join them, check out our programs and register in advance by clicking here.
