Florida C.R.E.W. Hardwood Hummock – Part 2

This is a description of the grassy and herbaceous undergrowth of this small part of the C.R.E.W. Together with the Part 1 post, the purpose of this presentation is to reduce the confusion of seemingly random plants and to help you understand why you see the what and why of the plants you see when you explore this type of wilderness area.

The featured image shows the “American beauty berry” in the understory. It was found along the trail to the live oak hummock on the path in the C.R.E.W. Cyprus Dome Cypress Hummock. This is second of a two part presentation of this area. The part one has the GPS location, charts and maps and describes the walk-about of the Corkscrew Reserve Environmental Watershed.

Perhaps the best way to understand the hydrology and geology for an area is to look at the plants. They have adapted themselves to use the area without the need to follow the resources like the animals. In fact the animals seek out the plants for survival. In these two presentations you can see the variances in plant anatomy and physiology through a series of locations. The plant adaptations have taken eons to reach the characteristics that make them identifiable as genus and apecies. The plants have the ability to adapt to the changing environment using two tools. These include plant succession and genetic mutation. Succession occurs when an ecosystem changes gradually or even catastrophically. This may cause the plant climax species to expire. Opportunistic species then overtake an available environmental niche. Mutations are genetic changes that take place at a known rate and this may result in variations which are better adapted to survive in an ecosystem. These mutations can be cumulative and can be perpetuated in the genome of subsequent progeny by inheritance of the variance.

This is a view into the scrub before the pond. From this distance the green mid-growth seems to be mangroves.

Observation of a confined area environment is a complicated but fun puzzle. The area should be visited during multiples of seasons, time of day intervals and length of observation to begin to grasp a comprehensive understanding of the area and begin to understand the reasons for classification and to understand the interactions of the plants and animals. Even simple identification is difficult when the plants are not blooming or in leaf. From this first time visit it can be discerned that there is a progression of plant types and land elevations in this small area. At the end of this presentation there is a simplified map of the area under observation. 

The undergrowth depends upon water, sunlight, soil minerals and a range of allelopathic inhibitors. Be sure that you check out part 1 of this series. This understory is very different from that found in the Estero River Scrub Preserve State Park. We will go there in the near future.

Here is a recommendation. Go out into the nearby wilderness area. Pick a quiet spot and try to identify the type of environment classification you see or identify the undergrowth plants. It can be a fun and an educational challenge! Share your experiences or photos in the comment box below.
