Dagny Johnson Key Largo Hammock Botanical State Park - Safari Today

Dagny Johnson Key Largo Hammock Botanical State Park. Take a stroll through a tropical forest and find the quiet that being in nature brings. Many visitors to Key Largo enjoy discovering the coral reefs, but often miss this gem. During the spring months, a visitor might still explore this tropical hardwood hammock without mosquitoes, but be prepared with insect repellent, just in case. Long sleeves and pants are recommended as we get closer to the wetter summer season, when mosquitoes are more likely. There is a self-guided nature walk, which includes a native plant butterfly garden and a picnic table for your enjoyment (please pack out your trash). An additional 6 miles of backcountry trails are yours to explore simply by completing a backcountry permit at the John Pennekamp Coral Reef State Park Ranger Station.(read more)

Thanks to my friend Ernesto for his help and company with thousands of mosquitoes today!!

The Liguus Tree Snails of South Florida by Henry T. Close
" Fifty nine names have been given to the colors forms of the Florida Liguus, many of them based on very subtle distinctions. For the most part, these forms are distinguished by colors ans patterns rather than by shape or texture. The basic Liguus are shades of yellow (including orange, brown, and black), gray and pink with occasional blues. Many of the spiral lines are green or bronze."
Henry T. Close

"The reasons for the extinction or reduction of the tree snail coloniesin most of the hammocks are evident. The actual instances ofextinctionare owing to one or the other, or a combination, of the following:
(1) Complete destruction of the hammocks either by clearing, building
of roads or houses, or removal of soil and rock.
(2) Profound modificationof the hammocks floor resulting from burning or from deposition
of rock, sand, or other material, either by man or natural agencies.
(3)Reduction of the population below an undetermined critical point or
reproduction by removal of snails by amateur or professional collectors,
natural enemies, or fire. In general, natural factors are of little or no
significance in regard to the rapid reduction and extinction which has
gone on in recent years."
Frank N. Young, April27, 1951

Liguus fasciatus SSC (Species of Special Concern) has a significant vulnerability to habitat modification, environmental alteration, human disturbance, or human exploitation which, in the foreseeable future, may result in its becoming a threatened species unless appropriate protective or management techniques are initiated or maintained.(pdf)

I've spent some time catching up on your all of your post since I was last here. Very informative, I only wish I visited Fl more often and could visit some of the wonderful places you profile so well.
