Alabama Ancient Savanna Species List

[edit]
An Oak Savanna

The U.S. state of Alabama from an estimated 129,000 years ago to approximately 300 years ago was a mix of open grasslands and savannas, in contrast to the closed canopy forests which cover most of the state today. Most of these savannas were a mixture of pine savannas and oak savannas with areas lacking any trees being basic open grasslands. This habitat was somewhat similar to the modern savannas of Africa although the main difference being the temperature. While summer months were hot and somewhat dry with temperatures ranging from estimated highs of 85°F – 100°F, winter months were cold and wet with lows reaching down to an estimated -20°F – 10°F. The landscape was comprised primarily of a variety of trees growing sparsely over a large area such as Longleaf Pines, Shortleaf Pines, Loblolly Pines, Southern Red Oaks, Cherrybark Oaks, Black Oaks, Blackjack Oaks, Eastern White Oaks, Chinquapin Oaks, Chestnut Oaks, Post Oaks, Sand Post Oaks, Sweetgums, Poplars, Cherries, and Plums The landscape was also dominated by many extinct animal species such as Short faced bear, Columbian mammoth, American mastodon, Great bison, Wild horses, American camels, Giant ground sloths, Dire wolfs, American lions, and the American cheetah.

The fauna of the state began a sharp decline approximately 12,000 years ago after the Younger Dyras impact. The impact is theorized to be a comet impact which rapidly cooled the earth followed by rapid heating which killed roughly 66% of all fauna species in the state.

Very little of the original savanna remains intact today due to human interference, primarily through fire suppression. Some modern analogs of the ancient savanna can be found in any large area that is cleared due to a dormant seed bank that sprouts after soil disturbance and sunlight exposure or in man made pine forests that is used for timber products. While these timber lands rarely experience fire, regular clearing and disturbance can result in an environment similar to the ancient savanna.

Many of the ancient savanna tree species are at risk of extinction within the state, possibly within the next 75 - 400 years due to fire suppression and unfavorable growing conditions such as shade cause by thick undergrowth or a closed canopy, and too thick of leaf litter. Trees such as the Longleaf Pine and Shortleaf Pine are expected to be possibly extinct within the next 100 - 250 years while trees such as the Cherrybark Oak, Eastern White Oak, Chinquapin Oak, Chestnut Oak, Post Oak and Sand Post Oak are believed to all be at risk of possible extinction within the next 200 - 400 years. In an even shorter time span the 6 American Plum species are all believed to be at risk of possible extinction within the next 75 - 150 years.

Efforts to combat this habit loss and possible extinction are being undertaken by some groups through land management projects aimed at improving conditions favorable to the trees and through the promotion of fire regimes.
