lings 1988). In particular, there is strong evidence to indicate that habitats with a grass-dominated ground cover were maintained by frequent, often low-intensity, fires prior to European settlement (e.g. Barbour et al. 1980, Christensen 1988, Sims 1988). Without fire, the vegetation of prairies, odysphagia 发表于 2025-3-24 04:29:46

For this reason, privately owned woodlands, including those used for grazing, are a major element in long-term conservation in the Midwest, and farm activities that affect woodland habitat function deserve specific attention.conceal 发表于 2025-3-24 07:29:15

Book 1979he health care most Americans receive will be-and should be-determined at the local level. To let this happen without industry involvement would represent an abdication of both responsibility and opportunity. Fortunately, we see a growth of industry involvement, growth not just in terms of numbers b
