“…Studies in countries where planted Eucalyptus is not native have also yielded mixed results. Some studies have reported lower plant and animal diversity in Eucalyptus plantations relative to mature, native forests and some other forest types or seral stages [64][65][66][67][68][69]. In Brazil, for example, da Rocha et al [70] found fewer species of lizards, anurans, and selected invertebrate taxa in Eucalyptus plantations than in large remnants of primary Atlantic Forest.…”

Short rotation woody crops (SRWC), fast growing tree species that are harvested on short, repeated intervals, can augment traditional fiber sources. These crops have economic and environmental benefits stemming from their capability of supplying fiber on a reduced land base in close proximity to users and when sensitive sites cannot be accessed. Eucalyptus and Populus appear to be genera with the greatest potential to provide supplemental fiber in the U.S. Optimal productivity can be achieved through practices that overcome site limitations and by choosing the most appropriate sites, species, and clones. Some Eucalyptus species are potentially invasive, yet field studies across multiple continents suggest they are slower to disperse than predicted by risk assessments. Some studies have found lower plant and animal diversity in SRWC systems compared to mature, native forests, but greater than some alterative land uses and strongly influenced by stand management, land use history, and landscape context. Eucalyptus established in place of grasslands, arable lands, and, in some cases, native forests can reduce streamflow and lower water tables due to higher interception and transpiration rates but results vary widely, are scale dependent, and are most evident in drier regions.

“…Several studies within the EAM and Coastal forests have documented the altitudinal migration for some bird species (Burgess & Mlingwa, 2000; Cordeiro et al., 2006; Werema, 2014, 2015; Werema et al., 2016) including those that showing a remarkable difference between cold and hot season during this study. The abundance of some bird species increases during the hot season which coincides with the breeding season in EAM (John & Kabigumila, 2011). The study area was at high altitudes (approximately 1650–2300 m a.s.l) that altitudinal migrants had higher abundances during the hot season than during the cold season.…”

“…However, despite the significant threat that anthropogenic forest fires present to some of the EAM (Wurster & Burgess, 2005), there is little information on the impact of fires on the flora and fauna particularly in montane forests. Most of the studies in the EAM have focused on other types of disturbances such as deforestation and fragmentations (Newmark, 1998; Newmark & Stanley, 2011), plantations (John & Kabigumila, 2007, 2011), invasions of alien species and edge effects (Borghesio, 2012). In fact, the role of fires on forest bird communities is poorly understood in many parts of Tanzania, including biodiversity hotspots like EAM (Werema, 2014).…”

The Eastern Arc Mountains are part of the Eastern Afromontane global biodiversity hotspot with a remarkable concentration of endemic species. Wildfire is among the major threats to biodiversity of forested mountains. This study assessed the effect of forest fire on the vegetation and understory birds in the Magamba montane forest, 5 years post a major fire outbreak. Mist-net transects were used to sample understory birds. During the breeding season, active bird nests were searched using the time-constrained method in both burnt and unburnt forests. Vegetation plots were sampled along the mist-net transects, and shrubs and trees were identified and counted. The diversity of trees and shrubs, tree density per plot and canopy cover were significantly higher at unburnt than burnt sites with no difference in shrub density per plot. Bird species composition and number of nests between burnt and unburnt forests differed significantly with a considerable decline of forest interior bird specialists in burnt areas. An invasive plant species, Acacia melanoxylon, was found in dense groves within burnt sites and if not controlled, would escalate the fire regimes to further affecting plants and avian communities. Fire management, restoration and rehabilitation of burnt areas are among the immediate recommended actions.

West Usambara Mountains, Tanzania are famous for rich biodiversity and endemic species of plants and animals. Although there have been extensive studies on plant and animals species, litle atention has been given on abiotic factors inluencing their spatial distribution. Given rampant degradation of vegetation and associated consequence on biodiversity, knowledge on abiotic factors inluencing distribution of species along the landscape become pertinent for conservation. A study was carried out to explore abiotic factors impacting plant and animals species distribution. Soil, landform and land use/ cover were studied using grids of 20 m × 20 m using FAO Guidelines for Soil Proile and Habitat Descriptions. Soils were described, sampled for laboratory analysis. Spatial distribution of plant species were determined in the grids, and along the transects, every time estimating the percent cover and describing the habitat. Distribution of animal species was studied using both small mammals and rodent burrows as proxies. Trapping was done using diferent traps sizes, checking daily for animal caught, counting and retrapping. Rodent burrows were estimated in same grids by examining a width of 0.5 m from end to end of grid and total number of burrows recorded. Determination of species distribution was done using GLM regression. Results show that species are inluenced by elevation, which was common to both plants and animals. Topsoil soil depth was positive to plant species whereas hillshade, surface stones, cultivation and atmospheric temperature were negatively inluencing plant species. Rock outcrops, surface stones and cultivation were positively inluencing small mammals distribution. It is concluded that factors inluencing distribution of small mammals are elevation, surface stones, rock outcrop and cultivation. Factors inluencing plant species are elevation soil depth whereas cultivation, hillshade, surface stone and rock out crops negatively impact distribution. For conservation, it is recommended that the best steps are to stop human activities leading to depletion of plant species and accelerating soil erosion and allow for self-regeneration. Control of soil erosion strongly recommended as way of plant species re-establishment.
