Early Settlers in CREW

Europeans & Early American Settlers, the history of land use and its effect on our water resources and wildlife in CREW
Lakes of Flint Pen Strand

Water management in Florida today has evolved from the lessons of the past, as well as from changing philosophies about natural resources and the environment. Early Native Americans in Florida altered the land by building settlements, cultivating fields, building mounds, establishing transportation routes, and digging canals and fish ponds. European explorers and settlers arrived in the 1500s, but much of Florida, particularly the central and southern regions, remained relatively undeveloped until the last decades of the 19th century. Significant increases in population and tourism were contemporaneous with new development and developers directly and indirectly caused significant changes to the natural landscape and resources of the state (Purdum et al.).

Europeans & early American settlers:

The history of Florida’s human settlement for most of the past 14,000 years has been shaped by water. When Spanish explorers arrived in Florida in the 1500s, an estimated 350,000 Native Americans were living throughout the state almost exclusively near water filled regions (Bureau of Archaeological Research). At the time of the European contact in the late 16th century, the Spaniards identified the people of Southwest Florida as the Calusa. The Calusa occupied the coastal zone, however their political influence and trade network extended inland to the Lake Okeechobee basin.

Settlement of Lee County really began in the years following the Civil War. Government land surveys seeking out areas for settlement were also completed during this period, although CREW area surveys were left incomplete due to the “impracticable” nature of the swamp. Ultimately, even though people had lived in Florida for thousands of years prior to 1900, their overall impact had been minimal.

Historical & archaeological research at CREW:

Archaeological research on the CREW lands, which includes approximately 60,000 acres, have uncovered no prehistoric or historic artifacts (Halperin et al.). However, archaeologically significant sites were identified adjacent to the CREW lands near Lake Trafford and several potential sites with historical resources were identified within the CREW project. Even though archaeological research uncovered no diagnostic artifacts and given the limited excavation done, it is reasonable to assume CREW would have been used for hunting and gathering activity by prehistoric peoples. Feel free to contact the CREW Trust or the Bureau of Archaeological Research if you discover a possible historical/archaeological site.

The early 1940s aerial photographs show limited cultural activity within the CREW project and by the 1970s, only a partial ditch system was in place. The Flint Pen Strand canals were more recently constructed, as evidenced by the dirt and rubble leftover from excavation. Some time after 1970, 12 to 15 homesteads were established in the slightly higher eastern part of the CREW project. The sites appear to have been selected based on slight elevations and access via the dirt trails. Almost nothing remains of these homesteads except abandoned power poles and a thin scatter of debris (Halperin et al.). 

In 2010, the South Florida Water Management District (SFWMD) began steps to restore hydrologic functions within the CREW Flint Pen Strand area (Blog: History of  Flint Pen Strand: Part Two), just another example of Floridians actively seeking ways to preserve, protect and restore water resources in more recent years.

Environmental choices & change:

Since 1900, Florida has seen substantial changes in land and water use. General consensus viewed Florida as having too much water and as a result, many Floridians were focused on drainage, flood control and navigation (Purdum et al.). Historically, water resources were seen primarily for human use and therefore were controlled and modified to suit our needs. Now, the value and sustainability of our finite water resources are clear. Land managers (SFWMD) today are concerned with water quality protection, water supply and ensuring natural places like the CREW watershed are under protection and preserved for future generations (Purdum et al.).

Wildfile Q & A: Bird Call Vs. Bird Song

A Carolina Wren sings to define and defend its territory.

Q: What are the differences between a bird call and a bird song?

A young Red-bellied Woodpecker calls to its parent for food.

A: A bird call tends to serve a specific function and is primarily
innate rather than learned. A bird song is almost always learned and
is often customized by individual males.

EXAMPLES OF CALLS

Alarm calls alert every bird within hearing range that danger is
present, and all innately understand what the call means and act
accordingly. The alarm call of one species can be recognized by birds
of many other species.

Location calls let mates or birds in a flock know where the others
are. For example, when a Barred Owl calls during the day, a mate often
answers, sometimes from a good distance away. Each then knows where
the other is. Location calls can also identify good feeding and
nesting habitats.

A chick’s “feed me” call triggers a parental response to find and
bring food to its offspring. As the chicks get older, begging behavior
complements the call for food.

EXAMPLES OF SONGS

Male birds tend to sing more than females, and unmated males sing more
than mated ones. Males use songs to attract mates and to identify and
defend territory. The song warns other males to stay out of its
territory, and it invites females to come in. Males can recognize the
songs of neighbors and usually don’t pay any attention to them, but
they sing furiously if they hear the song of a stranger who might
enter their territory.

In selecting a mate, females may use the size and complexity of the
song to determine a male’s potential fitness as a partner. More mature
males usually have more elaborate songs which may indicate to the
female that the male is a survivor with more breeding experience and
better health.

A majority of songbirds have at least two different songs. The extreme
singer is the male Brown Thrasher which is estimated to have over
3,000 song types.

Wildfile Q& A: Do all spiders bite, and are they poisonous?

Q: Do all spiders bite, and are they poisonous?

A: There are two problems with this question: a technicality, and a set of false assumptions.

First, the technicality. “Poisonous” and “venomous” are two different things. No spider is poisonous — harmful to eat, breathe, or touch. Mushrooms are sometimes poisonous, but spiders are not. Spiders are venomous; their toxins are proteins which only work when injected.

Second, all spiders do bite, but most local spiders are harmless because they are not aggressive and will not bite indiscriminately, or their fangs are simply too small to nip through our comparatively thick skin. Just because they are venomous does not mean they are
dangerous to people.

Spider venom does not exist to harm creatures which are too large for spiders to eat, like humans. The purpose of spider venom is to subdue the spider’s prey, almost always insects. In brief, it’s an insecticide.

Nevertheless, all larger spiders with a body length of a half inch or more should be treated with caution. Avoid flicking them away from your body. People allergic to bee stings may react more strongly to the bite of a spider than an ordinary person.

Bees and wasps kill more people in the United States in one year than spiders and snakes combined kill in ten years, and dogs and cats kill or injure more people each year than bees and wasps. Yet most people like dogs and cats and fear spiders and snakes.

SFWMD Land Assessment Draft Recommendations Ready for Review

As you know, most of the CREW lands are owned by the South Florida Water Management District. The District is currently conducting a Lands Assessment of all the lands they hold within the 16-county region they govern. The assessment is to determine if there are some parcels that could be surplused.

Back in May, we told you about the opportunity to provide public comment on the Lands Assessment. You all did a fabulous job of submitting comments. You can see them here. You can also download additional documents from here.

Today (July 30), the District is holding another public hearing for comment on the DRAFT staff recommendations which resulted from your earlier public comment. The meeting will be held at the SFWMD West Coast Service Center Office on McGregor Blvd. in Ft. Myers at 10 AM this morning (July 30). If you cannot make the meeting, additional public comment will be accepted online between now and August 12th.

Thank you all for your participation in this important process and for submitting your thoughts about CREW. It takes everyone’s participation to make sure sound decisions are made.
