“…Since the postindependence era, large‐scale mining in Sub‐Saharan Africa countries has been increasing, yet empirical information on post‐mining landscape restoration remains scarce (Festin et al, 2019; Venkateswarlu et al, 2016). In Kenya, with exception of very few cases such as the exhausted quarries of Bamburi Haller Park, Mombasa (Siachoono, 2010), most post‐quarry sites are minimally rehabilitated and then abandoned after closure of mining. Land owners and quarry operators cite high costs of rehabilitation as key reason for noncompliance which is compounded with weak legislation and enforcement regarding requirements for post‐quarry site rehabilitation (GoK, 2016; NEMA, 2020; Opondo et al, 2022; Waweru et al, 2018).…”

Abandoned post‐quarry sites have potentiality to be remodeled into natural‐wilderness areas, a desire especially in rapidly urbanizing and transforming landscapes. However, paucity of ecological information on post‐quarry sites limits nature‐based restoration, especially in the sub‐Saharan tropical landscape. This study investigated avifauna composition of post‐quarry sites in Ndarugu, Kenya, relative to non‐quarried sites for conservation role prioritization. Birds were censused in 166 point count stations using the fixed‐radius distance method. Land use land cover types within each point provided the variables for explaining bird occurrence. Observed bird species were classified into functional guilds, avifaunal composition assessed, and bird data subjected to multivariate analysis. In total 158 species, 128 in post‐quarry and 123 in non‐quarried sites, were recorded. Bush‐ and forest‐related species were dominant, constituting over 55% of total observed birds, in both site categories. Six wetland‐related species were detected only in quarried sampling sites. Mann–Whitney statistical tests returned a significant effect of land use category on bird species richness, abundance, and diversity, all higher in post‐quarried than in non‐quarried sites (p < 0.05). Emergent natural shrubs, quarry cliffs, and cultivated farms were most influential to bird community structuring. Nonmetric multidimensional scaling and cluster analysis revealed four functional groups of birds whose species richness increased with number of post‐quarried sampling sites in a cluster. Unique physical features of post‐quarry sites and emergent vegetation types, can be partially mimicked in nature‐oriented rehabilitation planning for long‐term social and ecological benefits.

1. Forests provide an immense range of benefits to people, many of which are not prioritized by forest policy because they are difficult to quantify. Wild foods from forests enhance the quality of diets for those who consume them and provide income for those who sell or trade them. The quantity of wild food collected is challenging to measure because of non-standard units, seasonal differences in collection patterns and large numbers of species. 2. To provide initial estimates of collection volume in Zambia and pilot new methods, we surveyed 209 households across 14 villages randomly selected within 5 study areas covering all four agro-ecological areas between 6 August and 27 October, 2019. For each study area, we conducted a focus group to identify the most commonly collected species within each of nine food product types (mushrooms, insects, green leafy vegetables, tubers, fruits, nuts, wild meat, wild fish, and aquatic plants).3. All but one surveyed household collected some wild foods; on average, each household collected five types of food product, most commonly mushrooms, fruits and green leafy vegetables. Volume collected varied markedly by household, product type and study area. Rural households in Zambia are estimated to collect over 380 million litres, 380,000 m 3 , of wild foods annually. We estimate that 88% of these wild foods are collected directly from forests. Accounting for uncertainties, we estimate the volume of wild foods collected from forests to be at least 238,000 m 3 per year, 125% of the volume of sawnwood produced, or about 12 million large (20 L) collecting buckets. 4. Volume collected was not strongly correlated with metrics of wealth, indicating ubiquitous consumption of wild foods; however, the most food insecure collected particularly high volumes of wild food. Pilot market surveys found local value chains for wild foods, indicating a potential for economic contribution.Our results underscore the value of data that can be disaggregated locally and indicate that national estimates of quantities of wild food collected from forests would be highly useful for designing forest policy and management strategies.
