“…The selected areas were then grouped into four categories, according to fallow age: young fallows (range 7-8 yrs), medium-aged fallows (range [10][11][12][13][14] were divided into ten 100 m 2 subplots [33]. A total of forty plots were surveyed, corresponding to ten mature stands and ten in each of the fallow stages.…”

“…This agricultural system has been labeled as the most serious land use problem and a major driver of deforestation in tropical areas of Africa [9,10]. It has been, however, an ideal solution for soil fertility in the humid tropics, at least in the past when the human population density was low and fallow periods were long enough to restore soil fertility [11,12].…”

The study was carried out in the Cusseque area of the Municipality of Chitembo in south-central Angola. Our objectives were to assess the floristic diversity, the species composition, and stand structure of Miombo woodlands during regeneration after shifting cultivation. A total of 40 plots of 1000 m 2 were surveyed and analyzed, corresponding to mature forests/woodlands and three fallow types of different age. The analyses were based on plot inventories of all trees with DBH ≥ 5 cm. A total of 51 woody species, 38 genera, and 19 families were recorded. The dominant family was Fabaceae, with subfamily Caesalpinioideae being very abundant. Shannon Diversity and Evenness were highest in mature forests and young fallows, while the mature forest stands showed the highest species richness. A Principal Coordinates Analysis (PCoA) showed many species shared between the intermediate fallow types, but only few species were shared with young fallows. Mature forests formed a clearly distinct group. This study shows potential pathways of forest recovery in terms of faster regeneration after agricultural abandonment and, thus, the results presented here can be used in future conservation and management plans in order to reduce the pressure on mature forests.

“…Community recovery can be accelerated when comparatively large forest area share a border with shifting cultivation site, in comparison with recovery in sites with shorter fallow cycles in the absence of adjoining forests, which act as sources for recolonization of vegetation [28].…”

The recovery of forest after shifting cultivation (locally known as 'jhum') has multiple complications as observed in various forest types, disturbed regimes, climate conditions and so forth. Rate of recovery and species composition are of major concern to understand the process of succession. The present study was carried out in Champhai district of Mizoram, India with the aim to comprehend the recovery of vegetation at different stages of succession after abandonment. Jhum fields of 5, 10, 15 and 25 fallow ages were located from the satellite imagery and the plot was navigated using GPS. Quadrats were randomly laid within those plots and the plants were enumerated and analysed. The species were contiguously distributed. Ecological indices indicated high diversity and species richness for tree and shrub components but low diversity and species richness for herbaceous component. The number of tree species declined by 5.1% from 5 years fallow to 10 years fallow. However, it increases from 10 years to 15 years fallow by 8.1% and was further enhanced to 32.5% on 25 years fallow. It was also observed that the number of shrub species declined from 5 years to 10 years fallow by 4.9% which worsened to 15.4% on 15 years fallow. Nevertheless, there was a distinct rise in the number of species on the 25 years fallow by 54.6%. Interestingly, the number of herbaceous species was observed to decrease from 5 years to 10 years fallow by 6.8% and further declined by 2.4% and 17.5% on 15 years and 25 years fallow, respectively. Therefore, the percent recovery of tree and shrub species from 5 years to 25 years fallow was 35.9% and 24.4%, respectively, while 25.0% of herb species declined during the same fallow period.

“…It has been pointed out that large sampling scale studies incorporate the effects of surrounding habitat and therefore reflect bird diversity in the agriculture-fallow-forest matrix rather than the diversity in each habitat specifically [2]. This assumption is based on previous large-scale secondary studies indicating a negligible effect on bird diversity [e.g., [39][40][41][42], whereas other studies [19,43] have shown that diversity is affected in small-scale studies that do not make up a matrix of surrounding primary (or close to primary) habitats and edge habitats.…”

“…Changes in bird communities may reveal successional processes going on in cleared forest. For example, analysis of bird-species inventories from 10 studies revealed that up to 70% of mature forest bird communities may recover in successional sites, and that species composition is about 55% similar to that of mature forests within 25 years [2].…”

Bird Abundances in Primary and Secondary Growths in Papua New Guinea: A Preliminary Assessment

Papua New Guinea is the third largest remaining area of tropical forest after the Amazon and Congo basins. However, the growing intensity of large-scale slash-and-burn agriculture and logging call for conservation research to assess how local people´s traditional land-use practices result in conservation of local biodiversity, of which a species-rich and diverse component is the avian community. With this in mind, I conducted a preliminary survey of birds in small-scale secondary plots and in adjacent primary forest in Wanang Conservation Area in Papua New Guinea. I used mist-netting, point counts, and transect walks to compare the bird communities of 7-year-old secondary growth, and neighboring primary forest. The preliminary survey lasted 10 days and was conducted during the dry season (July) of 2008. I found no significant differences in summed bird abundances between forest types. However, species richness was higher in primary forest (98 species) than in secondary (78 species). The response of individual feeding guilds was also variable. Two habitats differed mainly in presence of canopy frugivores, which were more abundant (more than 80%) in primary than in secondary forests. A large difference (70%) was found also in understory and mid-story insectivores. Species occurring mainly in secondary forest were Hooded Butcherbird (Cracticus cassicus), Brown Oriole (Oriolus szalayi), and Helmeted Friarbird (Philemon buceroides). Examples of primary forest species were Red-bellied Pitta (Pitta erythrogaster), Little Kingfisher (Alcedo pusilla), and Zoe's Imperial Pigeon (Ducula zoeae). My results suggest that changes in bird assemblages occur even in relatively undisturbed landscapes in response to small-scale shifting agriculture that is crucial for local people's livelihood; it also seems that traditional land use by local people favors the persistence of a rich bird species pool in the forested and traditionally managed landscape.
