Gopher tortoises still holding on in the flatwoods

September 24, 2026

Five observations recorded between September 19 and 20 confirm ongoing presence of this federally threatened keystone species in the area. As a keystone species, gopher tortoise burrows provide shelter for at least 360 other animal species, making their presence fundamental to ecosystem function.

Monarchs pass through Seminole on migration south

September 24, 2026

Nine monarchs observed on September 20 at 86th Way N, Seminole, FL, confirming passage through the region during the fall migration to Mexico. The species is proposed for threatened listing under the Endangered Species Act. September migration timing and concentration indicate normal phenological movement, with this ecosystem serving as stopover habitat.

Extreme drought eases across Pinellas County

September 24, 2026

Extreme drought conditions across Pinellas County improved substantially from mid-July through September, dropping from 100% of the county at D3 Extreme Drought or worse during July 14-August 3 to 14.11% as of late September. This recovery reduces water stress on plants including threatened mangrove species.

Red mangroves shelter nesting wading birds

May 27, 2026

The air hangs thick with salt and humidity above the mangrove islands near Palm City, where red mangroves rise from the water on their distinctive prop roots. Early summer brings a particular energy to these tidal edges. The water laps quietly against the aerial roots, creating small sounds that carry across the still surface. White ibises have claimed the red mangroves as their nursery. These curved-billed waders build their stick nests in the sturdy branches, fifteen to twenty feet above the water. The mangroves offer what few other trees can: a foundation that flexes with storm winds without breaking, branches strong enough to hold multiple nests, and isolation from ground predators. The ibises arrive in small flocks, their white plumage stark against the dark green mangrove leaves. They probe the nearby shallows for crayfish and small fish, then return to feed their young with partially digested food passed beak to beak. The red mangroves create this nesting sanctuary through their peculiar architecture. Their prop roots form a maze that few land predators can navigate, while the canopy provides shelter from above. Each tree anchors itself with dozens of arching roots that dive into the sediment, creating a living fortress. The boat-tailed grackles nest here too, the glossy black males and brown females weaving their cup nests into the outer branches. They scavenge along the tide line and steal food from other birds, but they also serve as sentries, their harsh calls alerting the colony to approaching threats. The invasive brown anoles climb through the lower branches, hunting insects but staying clear of the nesting areas where adult birds defend aggressively. This partnership between mangrove and bird shapes the coastal landscape. The ibises and grackles drop guano that fertilizes the mangrove roots, while their presence deters herbivorous crabs that might damage young mangrove shoots. The birds require the specific conditions that only red mangroves provide: stable branches over water deep enough to deter raccoons and snakes, yet shallow enough for wading and feeding. As the young birds grow stronger, their parents lead them on longer foraging flights to the lanceleaf arrowhead beds and open water beyond the mangrove edge. The adult ibises probe methodically through the shallows, their sensitive bills detecting movement in the murky water.
