Hot in the city – Can tree seedlings from urban areas beat the heat?
Urban development is expanding rapidly, leaving a patchwork of small, isolated forests in its wake. Urban areas tend to have more paved surfaces that retain heat leading to an urban heat island effect. Nearby, forests are subjected to higher temperatures leading to higher evaporative demand from leaf surfaces while soil compaction and altered water flow can lead to limited soil water availability. This may be particularly detrimental for young seedlings that are vulnerable to desiccation.Read more

Presenting Science Virtually
Information sharing is the cornerstone of science. Scientific conferences are a key venue for this information sharing – places where scientists present recent findings and hear what others are working on. Scientists, including the researchers at Holden, travel around the globe to share information with colleagues. As a scientist myself, attendance at conferences and invited seminars has become one of the best ways to learn about new research in the field ! However, in March of 2020, when it became necessary for us to stay socially distant due to COVID-19, in-person scientific conferences were cancelled.Read more

Research from the Burke Lab Published in Special Issue of Plants People Planet
David Burke, Sarah Kyker, Adam Hoke, Charlotte Hewins, and former summer intern, Catherine Chervanek have published research on mycorrhizal fungi that colonize root mats in the forest of Pierson Creek. Research on these root mats, which are dense tangles of mature tree roots just underneath the litter layer in the forest, began during Catherine’s summer internship. The research is published in a special issue of Plants People Planet on “Mycorrhizas for a changing world: Sustainability, conservation, and society” and can be read here.

Holden Awarded a Landscape Scale Restoration Grant
David Burke (Vice President for Science and Conservation) and Katie Stuble (Research Department Chair) were partners with Holden’s Conservation Department on a grant funded through the Landscape Scale Restoration Program. The project, titled “Making a Young Landscape Old: Landscape-scale forest restoration to promote biodiversity and resilience to environmental change,” will be conducted in the natural areas of Stebbins Gulch.

Holden Scientists and Volunteers Gear Up for Spring in the Forest
I had a moment of panic last week. It was the crocuses that did me in, if you can believe it! Well, the crocuses and climate change. I’m a scientist, and an experiment was on the line.
This year will mark four years of spring phenology monitoring in Bole Woods. Phenology is the study of the timing of natural events, and we’ve been monitoring the timing of the spring greening of Holden’s forests. This sort of monitoring helps us understand how species may (or may not) be able to track the changing climate, and anticipate potential changes in our natural world.

Holden Scientists were Wildly Curious about Wild Leek
The old growth remnant forests in Stebbins Gulch are locations at Holden Arboretum that David Burke and his lab have been studying for years. Burke first began hiking to the old growth portions of Stebbins Gulch back in 2006. One thing that he and Charlotte Hewins noticed every spring was the immense cover of wild leek (Allium tricoccum) on the forest floor. “Come April when the leeks are fully emerged, there is nowhere to step that isn’t completely covered in them,” Hewins once told me. In April of 2008, I saw it for myself and it took my breath away. Forest floors were supposed to be brown and covered in decaying leaves. But, the forest floor of Stebbins Gulch that April (and every April after) was green due to numerous wild leek leaves unfurling toward the sun!Read more

Detecting Changes in the Natural World
The Holden Arboretum is a stunning place to explore with its beautiful gardens and forests. I love to hike the trails with my family and watch the gardens transform over the seasons. But, as a scientist who studies the impacts of climate change, the Arboretum is also a treasure-trove of information. Natural areas like the ones protected by the Arboretum are increasingly rare and hugely important not only as sanctuaries for wildlife, but also as spaces in which to study it. And, given the stresses currently placed on the Earth, this role is perhaps more important today than ever.Read more

A Lady’s Slipper Update on the Eve of Orchids Forever
A lot of science and conservation is learning by doing, so I would like to provide an update on our lady’s slipper orchid conservation project. This is our first time growing orchids from seed. On December 11, 2020, Field Station Specialist Jing Wang and I sowed seeds of Cypripedium reginae, the showy lady’s slipper, collected in a Holden natural area. Details of the first steps can be seen in a previous blog entry here. It has now been nine weeks since we sowed the seeds, and we have good news to report. We have germination!Read more

Biotic Homogenization – Changes in biodiversity with urbanization in vacant lots
By Megan Herrmann, Graduate Student, Cleveland State University
The current biodiversity crisis seen in headlines has many overarching implications for ecosystems worldwide. Humans frequently aid in the dispersal of non-native species through both accidental and intentional introductions. Urban areas, as hotspots of human activity and disturbance, are thought to contribute to the spread of non-native species and create similar environmental pressures worldwide. Altogether, urbanization is thought to contribute to the increasing similarity of biotic communities, a process known as biotic homogenization.Read more

Stuble Lab Receives Invasive Plants Research Grant
Holden Scientist, Katie Stuble, and graduate student, Alexa Wagner, have received funding from the Ohio Invasive Plants Council. Their project, titled “Determining dynamics responsible for plant community responses to overstory thinning and invasive species management,” was awarded funding for $1,500. This support will help efforts to quantify the impacts management in Working Woods has on the survival and growth of young invasive species, as well as, the reproductive success of adult shrub species. This information will hopefully help predict restoration outcomes and inform management aiming to reestablish native plant communities.Read more

The Life Beneath the Snow
The month of January, with its freezing temperatures and leaf-less trees, is a time when it’s easy to think of nature as dormant. While this might be true for deciduous trees and hibernating animals, this is far from true for soil organisms, such as fungi. These decomposers are very active during the winter decomposing the leaf litter that fell just months prior! Snow cover is beneficial for this decomposition because it insulates the ground and keeps the soil from freezing. Snow cover does more than just keep the soil from freezing, it keeps soil temperatures stable. The soil ecology lab at HF&G has been monitoring soil temperatures in the forests of Stebbins Gulch since 2006. Soil temperature loggers record soil temperature every 8 minutes throughout the year. Year after year, soils in the winter are stable and typically just above freezing. Once the spring arrives and the snow cover is no longer constant, soil temperatures become much more variable. The now exposed soils can more easily freeze with cold night-time air temperatures and then thaw with the warmer air temperatures of the day.Read more
