Why Natural Regeneration Sometimes Fairs

Natural regeneration regenees on seed acvasibility, acsumble germination sites, and favorable microclimates. After seare fire, high- searity burn patches can extend hundreds of meters from unburned prevent edges, exceedissal range of many tree species. Soil hydrophobicity - created by fire-induced waxes - prevents water infiltion, leading to runofane erosion.

Creating Mikroklimatic Heterogeneity

Forest microclimates vary widely at fine scales. A shaded, north- facing microsite may be 5- 10 ° C cooler than an exposed patch. Structures that cass shade (log bundles, brush piles) lower surface temperatures andd reduce evarativa stres. This heterogeneity also supports a diversity of seed germination niches: some species require bare mineral soil (e.g., pines), whils need deep litter mos (e.g., hemlocks).

Poszukaj Dispersal Connectivity

Birds preferentially use these structures as stepping stone, transporting seeds from intact forests into recoveration zone.
