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.

Carbon sequestration and biodiversity following 18 years of active tropical forest restoration

BACKGROUND:

Vast tropical forests have been degraded and converted to other land uses such as agriculture. Degraded forests can regenerate naturally to improve biodiversity and carbon sequestration. However, major degradation factors, such as wildfires, hinder natural regeneration. Forest restoration can play an essential role in such circumstances. Nonetheless, research on methods to increase carbon storage and improve the ecosystem function of tropical forests is limited.

Co-benefits in biodiversity conservation and carbon stock during forest regeneration in a preserved tropical landscape

Background:

Recognizing the connection between carbon stock and biodiversity has become more crucial in light of the requirements set by international agreements. Consequently, a vital and indispensable measure for guiding relevant global environmental initiatives is to empirically investigating the potential advantages of restoring degraded areas through forest regeneration. This approach aims to boost both aboveground carbon stock and biodiversity, moving them closer to their natural levels.

Do primary rainforest tree species recruit into passively and actively restored tropical rainforest?

Background

In many restoration projects, recruitment is dominated by a low diversity of regionally-abundant pioneer species and species with small, easily dispersed seeds. These species are characteristic of secondary rainforest and do not include the far more diverse suite of species characteristic of the original, primary rainforest. As restoring ecosystem processes is one of the central goals of restoration, this raises the question of which, if any, of the available rainforest restoration methods may be used to promote the recruitment of primary rainforest species.

An overview of forest loss and restoration in the Brazilian Amazon

Background:

The accelerated process of forest loss and degradation in the Brazilian Amazon began in the 1970s due to government-promoted economic development initiatives. This led to significant deforestation, with approximately 20% (780,967 km2) of the region being affected . Nevertheless, the region still lacks scientific studies that reinforce the choice of best practices for forest restoration, and the information currently available is not enough to quantify what has already been recovered or the potential area to be restored.

Evaluating the success of direct seeding for tropical forest restoration over ten years

Background

The main causes of deforestation in the Amazon are large-scale agriculture and cattle ranching, which have led to the loss of millions of hectares of forest. To address this issue, different mechanisms have been implemented since 2005 to reduce deforestation and increase forest restoration.  However, highly modified, degraded areas with a long history of use may take a long time to regenerate naturally or may not recover into a secondary forest. Therefore, active restoration methods are needed to accomplish this massive obligation.

Restauración ecológica de bosques tropicales en Costa Rica: efecto de varios modelos en la producción, acumulación y descomposición de hojarasca

Background:

La deforestación altera los ciclos de nutrientes y aumenta la fuga de nutrientes del ecosistema con altos costos ambientales y sociales. No obstante, la deforestación sigue siendo intensa en la mayoría de los países tropicales, especialmente en América Latina, donde los bosques son talados y rápidamente convertidos para la agricultura. Así, las estrategias de restauración en los trópicos son indispensables considerando la gran escala de degradación y la necesidad de mantener procesos ecológicos vitales.

Desempeño de tres especies arbóreas del bosque tropical caducifolio en un ensayo de restauración ecológica

Background:

Este estudio es relevante, porque prácticamente no se ha generado información relacionada con el establecimiento de Albizia occidentalis y Cedrela dugesii en escenarios de restauración ecológica y además, estas especies están registradas bajo algún estatus de protección. La primera se encuentra en la categoría (A) como amenazada y la última sujeta a protección especial (Pr), debido a la distribución geográfica restringida que presentan ambas especies y el alarmante grado de transformación del hábitat en el Bajío Mexicano.

Tree Communities in Three-Year-Old Post-Mining Sites Under Different Forest Restoration Techniques in the Brazilian Amazon

Background:

Mining has been identified as a major contributor to forest loss, leading to the need for effective restoration techniques in post-mining sites. In this context, the knowledge of floristic composition is crucial for managing natural regeneration, selecting species for restoration plantings, and aiding conservation programs of threatened plant species. One well-known example of mining impacts on the Amazon rainforest vegetation is located in the Paragominas municipality, Pará, Brazil.

Mining in the Amazon: Importance, impacts, and challenges to restore degraded ecosystems. Are we on the right way?

Background:

With mining playing a significant role in the economies of Amazonian countries, there is a growing urgency to understand, mitigate, and restore the degraded ecosystems that result from these mining operations. These tasks present a complex set of challenges, including technological limitations, legal inconsistencies, and a shortage of qualified professionals.
