Out of steady state: Tracking canopy gap dynamics across Brazilian Amazon

Background

Canopy gaps are a regular characteristic of natural or anthropogenic disturbance in forested landscapes. Gap-creating disturbances often result in a forest mosaic with patches of varying successional stages. Many species in tropical forests depend on these canopy gaps for regeneration. Field monitoring of canopy gaps can be difficult due to time constraints and plot size, making tropical gap dynamics an understudied topic.

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.

Selecting tree species to restore forest under climate change conditions: Complementing species distribution models with field experimentation

Background

Climate-based species distribution models are used as a strategy to decide on optimal tree species for forest restoration projects. The criteria in these models is based on species performance in local climates. The limitation of species distribution models is that they do not include recruitment. Including the species successful reproduction, recruitment and growth at an early stage is vital for successful reforestation efforts. In addition, the models are not calibrated to take into account future climatic conditions, making it difficult to plan long-term restoration projects.

Trade-offs at applying tree nucleation to restore degraded high Andean forests in Colombia

Background

This article recognizes applied nucleation as a forest restoration strategy in many low to mid altitude forests and aims to compare applied nucleation to passive regeneration at high altitude forests. Applied nucleation is successful at accelerating the speed of forest regeneration, improving soil conditions, and shading out invasive species in many low-mid altitude forests of the neotropics. There are gaps in the literature about the performance of applied nucleation in other tropical regions as well as high attitude tropical forests.

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.

Why do foresters plant trees? Testing theories of bureaucratic decision-making in central India

Background

There is a long history of tree planting in India, and it continues to be favored by policy makers and bureaucrats at the state level. However, the author points out that the popularity of tree plantations is puzzling in the Indian case because firstly, it does not seem aligned with the goals of India’s forest policies which tend to emphasize ecosystem services rather than timber production and secondly, many degraded areas can regenerate naturally and do not require plantings to regenerate. This paper examines why tree plantations continue to be popular among state-level forest departments in India and how they are implemented in the field.
