Recreational Facilities of Conecuh National Forest

There are two developed National Forest recreation areas in Conecuh National Forest. Both are located along Alabama State Road 137 north of the community of Wing.

1. Open Pond Recreation Area

Open Pond Recreation Area is a 450 acre area set aside for hiking, fishing, bicycling, and camping. It is located about eight miles north of the Alabama/Florida State line along Alabama State Road 137. At the center of the recreation area is Open Pond, a natural sinkhole lake. Several other lakes are in the immediate vicinity of the facilities and can be reached by trail or on unpaved roads. Open Pond itself is available for freshwater fishing. A pier is available, and non-motorized or electric motorized boats are permitted on the lake (two boat ramps are available for launching). An Alabama fishing license is required. Also available is a large picnic shelter for group gatherings. No swimming is allowed at Open Pond.


Fees

Day use fees at Open Pond are USD$5 per vehicle. This allows for all recreational uses (picnics, hiking, bicycling, fishing, etc.). These fees may be waived if someone in the vehicle possesses a valid Federal Interagency Recreation Pass. Camping fees for non-electric sites are USD$6, and USD$12 for electric/water sites. Fifty percent discounts are available for camping fees when using the Federal Interagency Recreation Passes. Those paying for campsites do not have to pay day use fees.


Camping

Sixty-five campsites are available on a first-come, first-served basis at the Open Pond Campground. Campsites are found on the waterfront as well as in woodlands. There are four campground loops (A, B, C, and D). Roadways along all loops are paved.

The "A Loop" is primarily for tent camping, and water is available at spigots in the loop. There are no electric hookups in the A Loop. Restrooms and showers are available in the nearby "C Loop" a short walk away.

The "B Loop" is a group camping area. There are no hookups, restrooms, or showers in the "B Loop". The group camping area generally consists of a large field surrounded by woodlands, clearly separated from the developed camping loops. A trail connects to water supplies in the "A Loop". Restrooms and showers are a short hike away in the "C Loop".

The "C and D Loops" are both similar in that they provide recreational vehicles (RV) water electric hookups. 15, 30, and 50 Amp receptacles are available. Each site consists of a fine gravel pad for an RV, a pad for a tent, picnic table, and lantern hangar. Several sites are entirely concrete and are primarily for use as handicapped accessible. These loops contain modern restrooms and bath houses with hot showers.

An RV dump station is located at the entrance to the Open Pond Recreation Area.

Trails connect the "D Loop" of the campground to additional small sinkhole ponds and the day-use picnic areas. By using the roadway that begins at the picnic areas, hiking and bicycling around Open Pond is possible.


2. Blue Lake Recreation Area

Blue Lake Recreation Area is located about nine miles north of the Alabama/Florida State line off of Alabama State Road 137. This day use area, located along the north shore of Blue Lake, provides the only official location in Conecuh National Forest where swimming is permitted. A bath house is provided, along with picnic tables and a sandy beach. Limited non-motorized boating is permitted, and two boat launches area available.

Fees

There is a day use fee of USD$5 per vehicle. This allows for all recreational uses available at Blue Lake. These fees may be waived if someone in the vehicle possesses a valid Federal Interagency Recreation Pass.

Adjacent Land Use

The south, west, and eastern shores of Blue Lake are privately held by the Alabama-West Florida Conference of the United Methodist Church under the name "Blue Lake Methodist Assembly".

Conecuh National Forest

The Conecuh National Forest in southern Alabama covers 83,000 acres (340 km²), along the Alabama - Florida line in Covington and Escambia counties. Topography is level to moderately sloping, broad ridges with stream terraces and broad floodplains.

The Conecuh Trail winds 20 miles (30 km) through Alabama's coastal plain. The trail was built by the Youth Conservation Corps. Each year, beginning in 1976, the young people of the Corps extend the trail through park-like longleaf pine stands, hardwood bottomlands, and other plant communities of the Conecuh National Forest.

The name Conecuh is believed to be of Muskogee origin. It means "land of cane," which is appropriate because the trail runs through canebrakes in several sections.


Situated just above the Florida panhandle, the forest has a distinct southern flavor of mist-laden hardwood swamps, pitcher plant bogs, and southern coastal plain pine forest. These hilly coastal plains are also home to longleaf pine, upland scrub oak, and dogwood, as well as an aquatic labyrinth of winding creeks and cypress ponds.

Clear-cut in the 1930s, the Conecuh was reforested with slash pine that reduced the number of nesting trees for the endangered red-cockaded woodpecker. The forest is currently undergoing a reforestation from slash pine to the native longleaf. In time, this should increase the number of red-cockaded woodpeckers as the trees mature.

The forest is headquartered in Montgomery, as are all four National Forests in Alabama (Conecuh, Talladega, Tuskegee, and William B. Bankhead). There are local ranger district offices located in Andalusia.


U.S. National Forests

This is a list of all the National Forests in the United States. If looking at national forests on a map, be aware that, in general, those west of the Great Plains show the true extent of their area, while those east of the Great Plains generally only show purchase districts, within which usually only a minority of the land has been made national forest. As of September 30, 2007 there were 192,764,673 acres (301,194.8 sq mi, or 780,090.96 km²) of land managed by the United States Forest Service, an agency of the United States Department of Agriculture. The vast majority of the acreage is designated as either National Forests (97.2%) or National Grasslands (2.0%). There a few other minor categories, mostly "purchase units" and facilities related to research efforts. There is also one designated National Preserve (Valles Caldera National Preserve in New Mexico).


There is at least one National Forest in all but ten States: Connecticut, Delaware, Hawaii, Iowa, Kansas, Maryland, Massachusetts, North Dakota, New Jersey, Rhode Island, and in addition, there is a National Forest in the Commonwealth of Puerto Rico. Also, in quite a few of these ten states, there are either National Grasslands or substantial State Forests (e.g. New Jersey). Also, Hawaii, lacking either one of these, has two National Parks. Several states have both a National Park and a National Grassland; a few states have a National Forest, a National Grassland, and a National Park, e.g. South Dakota, California, Texas, and Colorado; and Michigan has a National Forest, a National Lakeshore, and a National Park. Also, Massachusetts, lacking any of these three, has the Cape Cod National Seashore.

The table below is sortable by state and alphabetically. For a more detailed breakdown by unit name, type designation, state, county, and congressional district, please refer to the official Forest Service report in the linked reference below.

Geographical variation and Biodiversity

Dry forests tend to exist north and south of the equator rain forest belt, south or north of the subtropical deserts, generally in two bands, one between 10° and 20°N latitude and the other between 20° and 30°S latitude. The most diverse dry forests in the world occur in southern Mexico and in the Bolivian lowlands. The dry forests of the Pacific Coast of northwestern South America support a wealth of unique species due to their dry climate. The subtropical forests of Maputo land-Ponderousin the sub-tropical regions of the United States of America and in southeastern Africa are diverse and support many endemic species. The dry forests of central India and Indochina are notable for their diverse large vertebrate faunas. Madagascar dry deciduous forests and New Caledonia dry forests are also highly distinctive (pronounced extremism and a large number of reliquary taxa) for a wide range of taxa and at higher taxonomic levels. Trees use underground water during the dry seasons.


Species tend to have wider ranges than moist forest species, although in some regions many species do display highly restricted ranges; most dry forest species are restricted to tropical dry forests, particularly in plants; beta diversity and alpha diversity high but typically lower than adjacent moist forests.

Effective conservation of dry broadleaf forests requires the preservation of large and continuous areas of forest. Large natural areas are required to maintain larger predators and other vertebrates, and to buffer sensitive species from hunting pressure. The persistence of riparian forests and water sources is critical for many dry forest species. Large swathes of intact forest are required to allow species to recover from occasional large events, like forest fires.

Dry forests are highly sensitive to excessive burning and deforestation; overgrazing and exotic species can also quickly alter natural communities; restoration is possible but challenging, particularly if degradation has been intense and persistent. Degrading dry broadleaf often leaves thorny shrublands, thickets, or dry grasslands in their place.

Tropical and subtropical dry broadleaf forests

The tropical and subtropical dry broadleaf forest biome, also known as tropical dry forest, is located at tropical and subtropical latitudes. Though these forests occur in climates that are warm year-round, and may receive several hundred centimeters of rain per year, they have long dry seasons which last several months and vary with geographic location. These seasonal droughts have great impact on all living things in the forest.

Deciduous trees predominate in most of these forests, and during the drought a leafless period occurs, which varies with species type. Because trees lose moisture through their leaves, the shedding of leaves allows trees such as teak and mountain ebony to conserve water during dry periods. The newly bare trees open up the canopy layer, enabling sunlight to reach ground level and facilitate the growth of thick underbrush. Trees on moister sites and those with access to ground water tend to be evergreen. Infertile sites also tend to support evergreen trees. Three tropical dry broadleaf forest ecoregions, the East Deccan dry evergreen forests, the Sri Lanka dry-zone dry evergreen forests, and the Southeastern Indochina dry evergreen forests, are characterized by evergreen trees.


Though less biologically diverse than rainforests, tropical dry forests are home to a wide variety of wildlife including monkeys, deer, large cats, parrots, various rodents, and ground dwelling birds. Mammalian biomass tends to be higher in dry forests than in rain forests, especially in Asian and African dry forests. Many of these species display extraordinary adaptations to the difficult climate.
This biome is alternately known as the tropical and subtropical dry forest biome or the tropical and subtropical deciduous forest biome. Locally some of these forests are also called monsoon forests, and they tend to merge into savannas.

Temperate broadleaf and mixed forest

Mixed forests are a temperate and humid biome. The typical structure of these forests includes four layers. The uppermost layer is the canopy composed of tall mature trees ranging from 33 to 66 m (100 to 200 feet) high. Below the canopy is the three-layered, shade-tolerant understory that is roughly 9 to 15 m (30 to 50 feet) shorter than the canopy. The top layer of the understory is the sub-canopy which is composed of smaller mature trees, saplings, and suppressed juvenile canopy layer trees awaiting an opening in the canopy. Below the sub-canopy is the shrub layer, composed of low growing woody plants. Typically the lowest growing (and most diverse) layer is the ground cover or herbaceous layer.

Trees

Characteristic dominant broadleaf trees in this biome include oaks (Quercus spp.), beeches (Fagus spp.), maples (Acer spp.), and birches (Betula spp.). The term "mixed forest" comes from the inclusion of coniferous trees as a canopy component of these forests. Typical coniferous trees include: Pines (Pinus spp.), firs (Abies spp.), and spruces (Picea spp.). In some areas of this biome the conifers may be a more important canopy species than the broadleaf species.


Climate

Temperate broadleaf and mixed forests occur in areas with distinct warm and cool season, which give it a moderate annual average temperature (3 to 15.6 °C). These forests occur in relatively warm and rainy climates, sometimes also with a distinct dry season. A dry season occurs in the winter in East Asia and in summer on the wet fringe of the Mediterranean climate zones. Other areas have a fairly even distribution of rainfall; annual rainfall is typically over 600 millimetres (24 inches) and often over 1500 millimetres (60 inches). Temperatures are typically moderate except in parts of Asia such as Ussuriland where temperate forests can occur despite very harsh conditions with very cold winters.

Protection of taiga

Many nations are taking direct steps to protect the ecology of the taiga by prohibiting logging, mining, oil and gas production, and other forms of development. In February 2010 the Canadian government established protection for 13,000 square kilometres of boreal forest by creating a new 10,700 square kilometre park reserve in the Mealy Mountains area of eastern Canada and a 3,000 square kilometre waterway provincial park that follows alongside the Eagle River from headwaters to sea. The taiga stores enormous quantities of carbon, possibly more than the temperate and tropical forests combined, much of it in peatland.

Natural disturbance

One of the biggest areas of research and a topic still full of unsolved questions is the recurring disturbance of fire and the role it plays in propagating the lichen woodland. The phenomenon of wildfire by lightning strike is the primary determinant of understory vegetation and because of this, it is considered to be predominate driving force behind community and ecosystem properties in the lichen woodland. The significance of fire is clearly evident when one considers that understory vegetation influences tree seedling germination in the short term and decomposition of biomass and nutrient availability in the long term. The recurrent cycle of large, damaging fire occurs approximately every 70 to 100 years. Understanding the dynamics of this ecosystem is entangled with discovering the successional paths that the vegetation exhibits after a fire. Trees, shrubs and lichens all recover from fire induced damage through vegetative reproduction as well as invasion by propagules.


Seeds that have fallen and become buried provide little help in re-establishment of a species. The reappearance of lichens is reasoned to occur because of varying conditions and light/nutrient availability in each different microstate. Several different studies have been done that have led to the formation of the theory that post-fire development can be propagated by any of four pathways: self replacement, species-dominance relay, species replacement, or gap-phase self replacement. Self replacement is simply the re-establishment of the pre-fire dominant species. Species-dominance relay is a sequential attempt of tree species to establish dominance in the canopy. Species replacement is when fires occur in sufficient frequency to interrupt species dominance relay. Gap-Phase Self-Replacement is the least common and so far has only been documented in Western Canada. It is a self replacement of the surviving species into the canopy gaps after a fire kills another species. The particular pathway taken after a fire disturbance depends on how the landscape is able to support trees as well as fire frequency. Fire frequency has a large role in shaping the original inception of the lower forest line of the lichen woodland taiga.




Centuries ago, the southern limits of lichen woodland taiga were only being formed It has been hypothesized and subsequently proved by Serge Payette that the Spruce-Moss forest ecosystem was changed into the lichen woodland biome due to the initiation of two compounded strong disturbances. The two disturbances were large fire and the appearance and attack of the spruce budworm. The spruce budworm is a deadly insect to the spruce populations in the southern regions of the taiga. J.P. Jasinski confirmed this theory five years later stating “Their [lichen woodlands] persistence , along with their previous moss forest histories and current occurrence adjacent to closed moss forests, indicate that they are an alternative stable state to the spruce–moss forests”.
