Old Growth Bald Cypress – Tupelo Forest 

“Old growth” forests are characterized by the accumulation of rich species diversity, multiple canopy levels, and tree size and age.  Additionally, the ecosystem services provided and the social, cultural, economic importance sets old growth forests apart from younger ones. In the United States, Indigenous cultural associations create the foundation of a deep historical relationship between humans and place defining habitat features (USFS & BLM, 2024).  Bald Cypress -Tupelo forests are on the verge of collapse across their historical range in the Southeastern U.S.  Collaborative research between the University of Virginia and Duke University recorded coastal forest wetland loss over a twenty year period and determined that 8% of the area was lost to varying causes.  One of the few habitat types that have been specifically targeted for destruction by the federal government, freshwater bald cypress swamps are crucial to sea level rise resilience and enduring extreme weather events (Bourne, Jr., 2023).

 The southern portion of the Blackwater River watershed, particularly the Blackwater River Preserve, is host to one of the best remaining examples of an old growth bald cypress – tupelo forest in the South East.  Individual bald cypress (Taxodium distichum) trees may be upwards of 800 years old.  Such sites offer valuable insight into the climate patterns of North America prior to colonization by Europeans (T.N.C. , n.d.).  The dominant species composition is a combination of Taxodium distichumNyssa aquatica (Water Tupelo) and Nyssa biflora (Swamp Tupelo).  These species coexist in a complicated relationship of competition and succession.  In sites that were historically logged, the two species of Nyssa tend to become more dominant due to their ability to rebound quicker from disturbance regimes.  Typically forests of this type are seasonally or semi permanently flooded up to 3 ft deep for parts of the year.
