Over 75% of all species of cacti are in decline, largely because of global environmental changes (GEC), including climate change.
Botanic gardens are living museums, offering opportunities for conservation and research as well as education, experience, and enjoyment through their plant collections.
Seed transfer guidelines and zones are used to manage the movement of plant materials, but by the end of the century many landscapes across the globe will have climates that are incompatible with current vegetation.
Restoration projects that support pollinators are becoming increasingly popular. Pollinating insects require resources, including nectar and pollen, throughout the growing season.
In 2012, more than two million acres of important sage-brush habitat burned in four Western States.
Native plant communities are key to ecosystem health, resiliency, and productivity.
Extinctions of species and subspecific taxa in hotspots of biodiversity deserve special attention. After more than 40 years of major efforts, estimates of extinct plant taxa in California seem to be somewhat stabilized.
Recent estimates indicate that one-fifth of botanical species worldwide are considered at risk of becoming extinct in the wild.
Impacts of global climate change, habitat loss, and other environmental changes on the world's biota and peoples continue to increase, especially on islands and in high elevation areas.
