Choosing an appropriate tie-in point (TIP) is a key to efficiently and safely work in a tree. A TIP that’s high and central in the crown provides maximum mobility for a climber, but the TIP also has to be strong enough to bear the loads associated with...

Greg reviews the key components to maintaining our stressed landscapes with tried and true Sustainable Landscape Management practices.

Speaker: Greg Paige, Director of Horticulture and Arboretum Curator, Bartlett Tree Research Laboratories and...

Join others in learning about the high diversity of plant species characteristics of the longleaf pine ecosystem and how it supports the many common and unique wildlife species in these open forests dominated by a single tree. Participants will also...

Trees grow with, and adjust to, large lateral and vertical loads caused by wind and gravity. Storms with strong winds and ice can push trees beyond their ability to reconfigure or fall back to reduce drag. Exceeding tree structural ice and wind load...

With increased intensification in cities throughout the world, urban trees are often at risk of becoming damaged by construction impacts, such as utility trenching or pavement / sidewalk repair. If the damage is severe and a tree loses a lot of its...

Two speakers will present restoration ecology research published in the January 2020 issue of the Natural Areas Journal: Leighton Reid will share understory plant community outcomes based on twelve years of monitoring in a woodland mosaic in Missouri...

This Plan is intended to outline plans for preparing for emergencies and for immediate response and short-term recovery efforts in an emergency. In addition, it contains plans for the security of the Arboretum's living and non-living collections and...

Join Jenica Allen and Bethany Bradley to learn about new tools for identifying and prioritizing range-shifting invasive plants coming soon to a landscape near you. Whether you’re a property owner, land manager, landscape professional, or policymaker,...

The Sustainable SITES Initiative is a set of comprehensive, voluntary guidelines together with a rating system that assesses the sustainable design, construction, and maintenance of landscapes. It is used by landscape architects, designers, engineers,...

Tree defects such as co-dominant leaders, girding roots and buried trunk flares, present at time of planting, cause failures and decline long after the warrantee period has expired.  Landscape architects may go to nurseries to tag trees; but often...

The effects of urban development write a profound signature on the landscape. Soils are inevitably compacted and regraded or paved over. We have developed techniques that can remediate these degraded soils and provide a long-term solution towards...

Seasonal color plants add to the beauty and ever-changing nature of the garden. These seasonal color plants each have different growing requirements, transportation distances, display durations, etc. In this presentation you will learn how a...

Weed management is often cited as the top production challenge in organic systems, and organic growers primarily manage weeds with soil disturbance. This method of weed control can be counterproductive to soil-health. This webinar will be a virtual...

UC has been heavily involved in research and extension efforts impacting landscape water conservation legislation for over 30 years. In 1981, UC implemented the California Irrigation Management Information System, a network of weather stations that...

A soil moisture sensor-based automated irrigation system was trialed in a commercial floriculture greenhouse to determine what benefits these types of systems may offer to herbaceous ornamental producers. Water use, crop quality and growth, and grower...

Understanding carbon footprint (CF) terminology and the science underlying its determination is important to minimizing the negative impacts of new product development and assessing positive or negative cradle-to-grave lifecycle impacts. Life cycle...

Supplemental lighting can enhance yield when sunlight is limited, as in winter. As the effect
of frequent cloudy or rainy days in other seasons on plant growth and yield remains unclear,
this article investigated the effect on tomato (...
