“…Nonetheless, there seemed to be a trend in which EP plots were more diverse than the AF plots (although not as diverse as SE plots) at higher elevations (Oosting 1942). This could be due to an altitudinal limit of distribution for Eupatotorium adenophorum, or less human activity in plantations at higher elevation, and consequently fewer invasions by E. adenophorum, since our results indicate that there is less E. adenophorum at the higher elevations.…”

Understory plant diversity assessment of Eucalyptus plantations over three vegetation types in Yunnan, China

Biodiversity in managed plantations has become an important issue for longterm sustainability of ecosystems. The environmental effects of plantations comprised of fast-growing introduced trees have been vigorously debated. On one hand, monocultures have been said to exhaust resources, resulting in decreased biodiversity. Conversely, it has been stated that monocultures may favor regeneration of undergrowth plants from surrounding forests, increasing biodiversity. In order to clarify the effects of planting Eucalyptus trees on species composition, diversity, and functional type of understory vegetation in Yunnan province, a field trial was implemented to compare Eucalyptus plantations (EPs) with two other local current vegetation types (secondary evergreen forests (SEs), and abandoned farmlands (AFs)). Each vegetation type was sampled in each of three elevational ranges (low = 1,000-1,400 meters above sea level (masl), medium = 1,400-1,800 masl, and high = 1,800-2,200 masl). Sample sites within each elevational range had similar environmental characteristics (slope, aspect, etc.). Thus, we sampled three vegetation types at each of three sites at each of three elevations for a total of 27 plots. We calculated relative abundance and importance value of species and diversity indexes to evaluate differences among local current vegetation types and elevational ranges, employing multivariate ordination analyses and other methods such as Analyses of Variance (ANOVA) and Indicator Species Analysis. We found that fast growing introduced Eucalyptus plantations led to reduced plant diversity in the study area, and that rare or threatened species were recorded almost exclusively in the SE plots, being essentially absent from the EP and AF plots. The understory plant diversity did not correlate with the altitude gradient significantly. Eucalyptus plantations (EPs) have a simpler community structure than that of either secondary evergreen forests (SEs; similar to natural state) or abandoned farmlands (AFs). No variable significantly explained variation of the understory shrub layer, but soil moisture-holding capacity and overstory coverage were significant in explaining variation of the understory herb layer, suggesting that the study of soil physical properties is necessary for better understanding of their importance in Eucalyptus plantations and other local current vegetation types.

“…These fires regulate numerous processes needed to maintain these communities (Christensen 1977;Wade and others 1980;Wright and Heinselman 1973). Periodic fire also knocks back the wall of hardwoods that continually invades adjacent upland sites (Barrett and Downs 1943;Chaiken 1949;Chapman 1947;Harcombe and others 1993;Heyward 1939;Long 1888;Oosting 1942;Platt and Schwartz 1990;Wahlenberg 1949;Wells 1928). As the time span between fires increases, the stature of the ever-present hardwoods also increases, shading out the herbaceous groundcover, thereby breaking up its continuity and ability to support spread of fire; this allows the hardwoods to further expand until they eventually dominate the site ( fig.…”

_____________________________________This state-of-knowledge review about the effects of fire on flora and fuels can assist land managers with ecosystem and fire management planning and in their efforts to inform others about the ecological role of fire. Chapter topics include fire regime classification, autecological effects of fire, fire regime characteristics and postfire plant community developments in ecosystems throughout the United States and Canada, global climate change, ecological principles of fire regimes, and practical considerations for managing fire in an ecosytem context.
