Hyparrhenia rufa

The soil C pool in different agroecosystems derived from the dry tropical forest of Guanacaste, Costa Rica

BACKGROUND:

Seasonally dry tropical forests, constituting 42% of all tropical forests, are critically endangered, with less than 0.1% protected in Pacific Mesoamerica. The preservation of these forests is severely threatened by the invasive, highly flammable grass Hyparrhenia rufa, which has aggressively colonized the area since the 1940s. The paper focuses on examining soil carbon pools across various ecosystems derived from these forests in Guanacaste, Costa Rica, emphasizing the urgent need for comprehensive research on their soil carbon dynamics.
