“…The ongoing forest conversion in our study area could indirectly contribute to the loss of those high conservation priority species. A substantial loss in grassland cover in our study landscape might also lead the local people to put additional pressure on the remaining forest area for grazing their animals that have influential factor in hindering natural regeneration [68][69][70]. Furthermore, the ongoing pressure supports expectations of Ciais et al [71] who predicted that the African forest carbon stocks would remain vulnerable.…”

“…Other implication associated with the increasing loss of the forest resource is the decline of biodiversity. According to Tesfaye et al [68] the remaining dry Afromontane forests of the study landscape are dominated by indigenous trees species among which some require high conservation priority. The same authors suggested in situ conservation efforts for those priority species including strict protection of the remaining mother trees.…”

Abstract:The objective of this study was to analyze land use/land cover (LULC) changes in the landscape of Munessa-Shashemene area of the Ethiopian highlands over a period of 39 years . Satellite images of Landsat MSS (1973), TM (1986), ETM+ (2000, and RapidEye (2012) were used. All images were classified using object-based image classification technique. Accuracy assessments were conducted for each reference year. Change analysis was carried out using post classification comparison in GIS. Nine LULCs were successfully captured with overall accuracies ranging from 85.7% to 93.2% and Kappa statistic of 0.822 to 0.924. The classification result revealed that grasslands (42.3%), natural forests (21%), and woodlands (11.4%) were dominant LULC types in 1973. In 2012, croplands (48.5%) were the major LULC types followed by others. The change result shows that a rapid reduction in woodland cover of 81.8%, 52.3%, and 36.1% occurred between the first (1973-1986), second (1986-2000), and third (2000-2012) study periods, respectively. Similarly, natural forests cover decreased by 26.1% during the first, 21.1% during the second, and 24.4% during the third periods. Grasslands also declined by 11.9, 17.5, and 21.1% during the three periods, respectively. On the contrary, croplands increased in all three periods by 131, 31.5, and 22.7%, respectively. Analysis of the 39-year change matrix revealed that about 60% of the land showed changes in LULC. Changes were OPEN ACCESS Remote Sens. 2013, 5 2412 also common along the slope gradient and agro-ecological zones with varying proportions. Further study is suggested to investigate detailed drivers and consequences of changes.

“…Based on the assessment of diameter class distributions, the population structure patterns of the woody species recorded from Island Safari, Shorobe and Xobe were categorized into two groups. In the first group, the number of individuals decreased with the increasing diameter class, resulting in an inverted J-shaped population, an indication of stable population structure or healthy regeneration status (Teketay 1997a;Alelign et al, 2007;Tesfaye et al, 2010;Zegeye et al, 2011;Helm & Witkowski, 2012;El-Sheikh, 2013). This pattern was exhibited by about 29%, 20% and 15% of the woody species recorded at Island Safari, Shorobe and Xobe, respectively.…”

Stand structure, diversity and regeneration status of woody species were investigated in open and exclosed dry woodland sites in Island Safari, Shorobe and Xobe, northeastern Botswana. A total of 105, 111 and 130 quadrats, measuring 20 × 20 m each, were laid down along parallel line transects in the three sites, respectively, to collect data. A total of 47 species, representing 16 families and 24 genera, were recorded in the study sites. Of these, 33 species representing 13 families and 20 genera, 41 species representing 15 families and 23 genera and 27 species representing 10 families and 14 genera were encountered in Island Safari, Shorobe and Xobe, respectively. The most diverse family was Fabaceae followed by Combretaceae and Tiliaceae at all the three sites. The most diverse genus was Acacia, followed by Combretum and Grewia. The diversity of woody species in the study sites were 2.18, 2.15 and 1. sii and A. luederitzii in Xobe. The alarming result was the fact that 71%, 80% and 85% of the woody species recorded in Island Safari, Shorobe and Xobe, respectively, exhibited hampered regeneration and, thus, unhealthy population structures. Therefore, there is an urgent need to address the observed unhealthy population structures of the woody species through investigation of the major causes of their hampered regeneration, and also designing measures that will facilitate natural and artificial regeneration of these species at the three study sites.

“…In order to cope up with harsh growth conditions, subalpine and alpine plants adopt periodicity and seasonality in growth pattern (Ram et al 1988;Nautiyal et al 2001;Viswanath et al 2002;Bisht et al 2013). Periodicity and seasonality in plants growth pattern is triggered by variety of biotic and abiotic factors (Tesfaye et al 2011) and understanding of phenological pattern is important for analyzing structure and function of plant communities (Sharma and Khanduri 2007;Yadav and Yadav 2008). Phenology of some representative trees, shrubs-under shrubs and herbaceous species in a subalpine forest of Uttarakhand, western Himalaya in relation to ambient growth conditions is reported in this communication.…”

Observations on phenology of some representative trees, shrubs, under-shrubs and herbs in a subalpine forest of Uttarakhand, western Himalaya were recorded. With the commencement of favorable growth season in April, occurrence of leaf fall was indicatory growth phenomenon in Quercus semecarpifolia, Q. floribunda and Abies spectabilis. However, active vegetative growth in herbaceous species starts onward April and fruit maturation and seed dehiscence are completed from mid of September to October. In general, vegetative growth and reproductive stages in majority of the studied species seems to be dependent on adequate moisture content and also flowering and fruiting in subalpine plants correlate ambient temperature.
