Despite growing recognition of the conservation values of grassy biomes, our understanding of how to maintain and restore biodiverse tropical grasslands (including savannas and open‐canopy grassy woodlands) remains limited. To incorporate grasslands into large‐scale restoration efforts, we synthesised existing ecological knowledge of tropical grassland resilience and approaches to plant community restoration. Tropical grassland plant communities are resilient to, and often dependent on, the… 

Seed ecology and grassland resilience : the case of campo rupestre

Our knowledge of tropical old-growth grassland resilience (i.e. resistance to degradation and capacity for recovery) remains limited relative to our knowledge of temperate grasslands. Although highly

Ecological Grassland Restoration—A South African Perspective

The principal drivers of Grassland Biome conversion and degradation in South Africa include agricultural intensification, plantation forestry, urban expansion and mining, together with invasive

A research agenda for the restoration of tropical and subtropical grasslands and savannas

Despite growing recognition of the conservation value of grassy biomes, our understanding of how to restore biodiverse tropical and subtropical grassy biomes (grasslands and savannas; TGB) remains

Restoring savannas and tropical herbaceous ecosystems

  • Environmental Science
  • 2020
When people think of savannas, they think of the vast African landscapes where elephants, wildebeest, giraffes or lions used to roam. With the seasons, the vegetation tall grasses more or less

Restoring tropical forest–grassland mosaics invaded by woody exotics

Although important for biological conservation and provisioning of several ecosystem services, tropical forest–grassland mosaics face several threats, one of which is woody invasion in grasslands of

Grasslands and savannahs in the UN Decade on Ecosystem Restoration

Grasslands and savannahs are suffering heavy losses from degradation and conversion. The UN Decade on Ecosystem Restoration offers important opportunities to address these losses through a range of

Changes in conservation value from grasslands to savannas to forests: How a temperate canopy cover gradient affects butterfly community composition

This work examined how butterfly community attributes in northwest Indiana USA, including community composition, richness, and abundance responded to a grassland-to-forest gradient of canopy cover, suggesting that habitats of intermediate canopy cover might be particularly effective for butterfly conservation in this region.

High plant diversity and slow assembly of old-growth grasslands

It is shown that after old-growth grasslands are destroyed, the recovery of plant diversity requires hundreds to thousands of years, which underscores the need to replace outdated models of forest succession with models that emphasize the importance of fire, herbivory, and long periods of time to grassland biodiversity.



South African grassland ecology and its restoration

Grasslands are considered to be the most threatened biome in South Africa and yet they are still generally misunderstood. Often ignored as part of the conservation estate, grasslands are viewed as

Grassland restoration after afforestation: No direction home?

Restored grasslands showed no increase in forb species richness with increasing time since clear-felling of pines, and current methods for restoring these grasslands are inadequate and that restoring grasslands may be a lot harder than previously thought.

Reforestation or conservation? The attributes of old growth grasslands in South Africa

A study comparing primary grasslands in South Africa with 4–40 year old secondary grasslands recovering from afforestation with Pinus species reports significantly higher plant species richness overall and differed in their fire response, showing significant post-burn resprouting and fire-stimulated flowering in contrast to secondary Grasslands.

No recovery of campo rupestre grasslands after gravel extraction: implications for conservation and restoration

Old‐growth grasslands, including savannas and tropical grasslands, need centuries to assemble; they are therefore expected to have low resilience to anthropogenic activities that disturb the soil

Passive restoration of subtropical grassland after abandonment of cultivation

Passive restoration of grasslands after the abandonment of cultivation may be a viable restoration option where seed sources from remnant grasslands are available, and if the risk of deflected

The original native pasture ecosystems of the eastern and western Darling Downs — can they be restored?

The original pasture ecosystems of southern inland Queensland ranged from treeless grasslands on cracking clays through grassy woodlands of varying density on a great range of soil types to those

The early response of subtropical tussock grasslands to restoration treatments

This study provides a practical assessment of the short-term impacts and capacity of common grassland restoration treatments to enhance the recovery of Australia's tussock grassland systems.

Grassland restoration on former croplands in Europe: an assessment of applicability of techniques and costs

Grasslands used to be vital landscape elements throughout Europe. Nowadays, the area of grasslands is dramatically reduced, especially in industrial countries. Grassland restoration is widely applied
