Needlecast and needle blight are terms applied to a variety of foliage disorders of many coniferous species. These diseases are usually more severe on young trees or on trees growing outside of their natural range.
As land-use patterns change over time, some pollinating insects continue to decline both in abundance and diversity. This is due, in part, to reductions in floral resources that provide sufficient nectar and pollen.
Thousands of trees are struck by lightning every year. These trees will have varying degrees of damage ranging from complete shattering and destruction of the tree, to a slow lingering death, to virtually no apparent damage at all (Figure 1).
Agriculture is comprised of managed ecosystems, which can include forests, rangelands
and crops; these managed ecosystems are vital resources, providing a host
Biodiversity in and across food and agriculture systems provides tremendous value to present and future generations. However, across the world we are losing genes, species, and ecosystems faster than we can account for them.
Despite the importance of bees, there is a gap in the public's understanding of them.
Crop wild relatives, the wild progenitors and closely related cousins of cultivated plant
species, are sources of valuable genetic resources for crop improvement. Persisting gaps
Urbanization is a large driver of biodiversity globally.
Climate Action Planning is designed to help planners, municipal staff and officials, citizens and others working at local levels to develop and implement plans to mitigate a community’s greenhouse gas emissions and increase the resilience of communities
An Urban Tree Canopy (UTC) assessment, which provides a measure of a community’s tree canopy cover, is important for understanding the extent of a community’s forest or tree resource.
