The potential of secondary forests to restore biodiversity of the lost forests in semi-deciduous West Africa

BACKGROUND:

The human population in West Africa has increased considerably over the past four decades, leading to a high demand for food. This has led to the conversion of vast forest lands to agricultural lands in the region. Degraded forest landscapes have the capacity to regain fertility and naturally regenerate, resulting in the widespread spread of secondary forests in West Africa. Despite the significant presence of secondary forests in the region, there is rare knowledge about forest successional stages and general dynamics.

Spatial patterns and drivers of smallholder oil palm expansion within peat swamp forests of Riau, Indonesia

Background

Tropical peat swamps are a major carbon sink, and therefore critical for meeting global climate goals. There is also rapid loss of these ecosystem types due to agriculture practices and drainage. Oil palm (Elaeis guineensis) is often planted in drained peat swamps for production. Policies in Indonesia drive smallholder oil palm farms into peatlands and prevent their access to industrial fields.

The eco-evolutionary history of Madagascar presents unique challenges to tropical forest restoration

Background

Madagascar forests contain high biodiversity and species endemism, while also being heavily threatened by deforestation. Restoration of these forests may be unique to many other restoration projects due to the unique evolutionary history of the island.

Goals and Methods

The authors conduct a literature review of publications to determine if forest restoration in Madagascar is more challenging. With compiled literature from 1990 to 2022, the authors consequently describe unique challenges to Madagascar forest restoration in order to facilitate higher quality restoration projects.

Linking disturbance history to current forest structure to assess the impact of disturbances in tropical dry forests

Background

Tropical dry forests are given less attention in studies compared to tropical humid forests, but they still experience high levels of disturbance, both natural and human-made. These disturbances heavily alter the characteristics of valuable remaining forest structures. There are gaps in knowledge about how the timing and type of disturbance affects forest structure in seasonally dry tropical forests.

Controlling invasive plant species in ecological restoration: A global review

Background

Invasive plant species are known to impede the growth and establishment of many native plant species while influencing other ecosystem features such as soil properties, fire regimes, hydrology, and human well-being. This article presents the findings of a literature review of 372 articles to better understand the impact of invasive species and control methods to highlight gaps in overall knowledge of the topic.

Filling a void: Analysis of early tropical soil and vegetative recovery under leguminous, post-coal mine reforestation plantations in East Kalimantan, Indonesia

BACKGROUND

Surface mining is a common practice for obtaining coal, the world’s leading energy source. Surface mining removes vegetation, soil, and rocks to extract resources. In Indonesia, the world’s fifth largest coal producer, coal mining companies are required to rehabilitate mined sites. Companies typically plant exotic legume tree species because they quickly achieve canopy closure, limit invasive weeds, improve soil nitrogen, and create a light environment that helps with the recruitment of woody plants. This article looks to see whether natural forest succession occurs under leguminous plantations at rehabilitated coal mines in East Kalimantan, Indonesia.
