In this episode, LGLCI Executive & Education Director Tara Morris sat down to chat with Brian Early, State Plant Community Ecologist for the Louisiana Department of Wildlife and Fisheries.
Brian shared a wealth of knowledge about the native flora and fauna of Louisiana, and their historical significance to the landscape. Additionally Brian gave insight to the benefits that planned land disturbances, such as grazing and/or prescribed fire, can have on the ecosystem.
Some additional notes from Brian:
10:33 – I was referring to several books and the General Land Office records:
- Lockett, Samuel. 1995 (L. Post, editor). A Geographical and Topographical Description of the State 1869-1872
- Darby, William. 1817. A Geographical Description of the State of Louisiana.
- Newton, Milton Jr. 1987. Louisiana A Gerographical Portrait.
- Hardy, Laurence, Edt. 2008. Freeman and Curtis Red River Expedition of 1806
- Louisiana State Wildlife Action Plan. 2025. https://www.wlf.louisiana.gov/assets/Resources/Publications/Wildlife_Action_Plans/2025-Louisiana-State-Wildlife-Action-Plan.pdf
- Office of State Lands, historical surveys and documents. https://wwwslodms.doa.la.gov/
12:32 – I mention we “had bison in every parish in Louisiana”. To clarify, we have had bison occurrences reported from every parish. The statement “had bison in every parish in Louisiana” to some may be interpreted as stable persisting population. On the contrary, the bison herds were largely migratory and grazing as they passed through.
18:13 – I mention either mammoth or mastodons were present in Louisiana historically. However, the fossil records show that both were present.
22:38 – The first law of thermodynamics is called conservation of energy, which states that energy cannot be created or destroyed, only transformed from one form to another.
23:00-24:00 – “Intact plant communities / intact plant systems” What I am referring to here is very mature old growth intact systems that have secured some high level of ecological stasis, where plant species assemblages are relatively stable, able to resist weedy and non-native encroachment, and buffer environmental changes.
35:00 – I did not answer this question very well and yes there is some loss of energy/mineral resources when live stock bulk up on the land and then removed.
36:56 – Over-grazing is even more of an issue on the contemporary landscape due to plant and animal habitat fragmentation, impeding plant and animal migrations and recolonizations. When conservative plant species (often-high forage quality species) are over-grazed or extirpated from a property, they rarely, if ever, return to the habitat.
