Fire-dependent pine forests in the Caribbean Basin cover extensive areas in the coastal plain of the Caribbean Sea and Gulf of Mexico and on several islands in the Bahamas Archipelago, Cuba, Hispaniola, and the Honduran Bay islands. These forests are high in conservation value but, unfortunately, remain mostly unprotected. Moreover, even though they are fire dependent, the use of fire for forest management often suffers from poor public perception and is prohibited by law in several countries. In this paper, we describe the fundamental links among fire, forest regeneration, and forest persistence in these ecosystems. We identify two general strategies based on the presence or absence of pine seedling adaptations for fire survival and describe management implications of these two strategies. We also introduce conceptual models describing fire, forest structure, and regeneration strategy linkages.
加勒比海盆地依赖火的松林覆盖了加勒比海和墨西哥湾沿海平原以及巴哈马群岛、古巴、伊斯帕尼奥拉岛和洪都拉斯湾群岛的几个岛屿上的大片区域。这些森林具有很高的保护价值,但遗憾的是,大部分仍未得到保护。此外,尽管它们依赖火,但在森林管理中使用火往往得不到公众的认可,并且在一些国家被法律禁止。在本文中,我们描述了这些生态系统中火、森林更新和森林持久性之间的基本联系。我们根据松树幼苗对火灾生存的适应情况的有无确定了两种一般策略,并描述了这两种策略的管理意义。我们还引入了描述火、森林结构和更新策略联系的概念模型。
