Ten years ago the Royal Botanic Gardens Victoria embarked on an ambitious project to collect, treat and distribute storm water from the catchment within and around the botanic garden. The infrastructure of wetlands filtration, a sophisticated water ...

Dr. Kay Havens, Chair of the PCA Non-Federal Cooperators Committee, will briefly report on the "Assessment of Native Seed Needs and Capacities" being conducted by the National Academies of Sciences, Engineering, and Medicine, including the phase 2 data...

It is widely recognized that actions aimed at conserving, restoring and sustainably manage nature will not only help address biodiversity loss and deterioration of ecosystems but also contribute to climate change mitigation, resilience and adaptation....

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. Disease severity and corresponding...

Sonic tomography, or the use of sound waves to detect decay in trees, is a relatively new technology available to arborists.  This technology uses the differential speed of sound as it moves through solid wood, decayed wood, or hollow space to create a...

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). When...

Oak decline is a slow-acting disease complex that involves the interaction of biotic and abiotic factors such as climate, site quality and advancing tree age. Oak decline occurs more commonly among red oak species, but white oaks are susceptible as...

Participants will learn about the potential impacts of climate change on 125 tree species of the eastern US. Changes in suitable habitat, capacity to cope with the changing climate, and potential for infilling or migration by the end of this century...
