Restoration potential of soil seed bank in a changing climate

Restoration potential of soil seed bank in a changing climate

In a recent special issue in Restoration Ecology, the main topics were seed dispersal and seed bank ecology. In one of the review papers published in that issue we synthesized the existing knowledge about the seed bank of various open habitats and the effect of climate change on them. Due to the very few direct climate manipulation studies in open habitats with respect to soil seed bank, we provided a new perspective to reveal the possible effect of climate change on the soil seed bank.

Ethical seed sourcing is a key issue in meeting global restoration targets

Ethical seed sourcing is a key issue in meeting global restoration targets

Hundreds of thousands of tonnes of wild seeds are needed to restore plant ecosystems globally but over harvesting risks their depletion unless ethical seed-sourcing regulations are developed, Curtin University research has found. A paper, just published in journal Current Biology, concluded that inadequate regulatory frameworks controlling wild-seed sourcing, limited farming capacity and seed wastage are impeding moves towards the sustainable practice of native-seed collection.

Soil seed banks: a sneak preview into the future

Soil seed banks: a sneak preview into the future

Many arid land plants possess seed dormancy, enabling them to delay germination until receiving environmental cues that stimulate development. Dormant seeds within the soil create seed banks that are a valuable resource for regeneration of native plant communities after disturbance. Seed germination and soil seed bank research is important to better understand soil seed bank dynamics, appropriately select restoration seed mixes, and gauge the restoration potential contained within existing soil seed banks.

Seed-based restoration of damaged Mediterranean coastal habitats: the Sardinia case

Seed-based restoration of damaged Mediterranean coastal habitats: the Sardinia case

The Mediterranean Basin is one of the most important plant diversity hotspots worldwide; however, its sandy coasts are affected by strong erosive processes, also accentuated by the disappearance of dune and submerged vegetation caused by human exploitation. Therefore, in the Mediterranean area the plant species conservation and ecological habitat restoration are of major importance for sustainable development.

The International Seed Society’s Second Seed Longevity Workshop

The International Seed Society’s Second Seed Longevity Workshop

The USDA Agricultural Research Service’s National Laboratory for Genetic Resources Preservation hosted the International Society for Seed Science’s (ISSS) Second Seed Longevity Workshop at Colorado State University in Fort Collins, on July 20 – August 1, 2018.  About 100 participants from 22 countries attended.  ISSS aims to foster and promote research, education and communication in the scientific understanding of seeds.  The workshop is held to discuss current findings and propose new directions for future research on seed longevity. Papers from the meeting will be available later in a Special Issue of Seed Science Research “Seeds, Conservation and Biodiversity”.

Roadside Revegetation – An Integrated Approach to Establishing native Plants and Pollinator Habitat and the Ecoregional Revegetation Application Tool

Roadside Revegetation – An Integrated Approach to Establishing native Plants and Pollinator Habitat and the Ecoregional Revegetation Application Tool

Roadsides can play an important role in the conservation of both native plants and declining wild and managed pollinator species.  In an effort to enhance the success of roadside revegetation projects and create habitat that is favorable for pollinators, the US Department of Agriculture, Forest Service (USFS) and Federal Highway Administration (FHWA) partnered with the Xerces Society for Invertebrate Conservation and Chicago Botanic Garden to release a new DRAFT manual:  Roadside Revegetation – An Integrated Approach to Establishing Native Plants and Pollinator Habitat.
