Thousands of trees are lost in urbanizing areas of Virginia each year to land development, storms, and pests. As a result, large amounts of tree debris, much of which could be suitable for high-value wood products, are flowing from Virginia’s urban forests annually. Finding cost-effective, sustainable strategies for recycling this debris, particularly into durable wood products that keep carbon stored, could benefit the local economy and the local environment throughout the state. To inform outreach and technical assistance efforts of multiple groups across the state, a survey study was conducted in the City of Harrisonburg to determine household perceptions and practices of tree debris recycling. A random sample of owner-occupied, single-family dwellings was contacted using a mixed-mode survey approach to determine why and how trees were removed from the properties in the past and how the debris was disposed of or recycled. Survey responses were received from 189 households, with survey responses pointing toward a strong community sentiment for trees and their care. Nearly all respondents agreed that wood from street trees, park trees, and other neighborhood trees should be recycled into products rather than disposed of in a landfill; however, the majority of households do not currently recycle woody debris from trees removed on these properties. The three most important factors that would facilitate future participation in tree recycling include timely removal of the wood, free curbside pick-up of the wood, and knowledge of who to contact to handle the wood. Overall, these results point to household interest and willingness to participate in wood recycling programs given appropriate information to guide their decisions and local services to facilitate transfer of wood to the municipality or commercial woodworkers. This suggests a need for greater availability of neighborhood or municipal wood recycling programs, ideally coupled with greater education and outreach about the economic and environmental benefits of recovering and utilizing wood from felled trees.

Though the urban forest resource has been the subject of numerous studies quantifying ecosystem benefits and assessing tree canopy cover, little is known about the managers of this resource – the urban foresters. Literature from more well-established professions shows they routinely reflect on their own profession to identify opportunities and areas for improvement. A few examples of topics addressed by these reflections are recruitment of youth into the profession, monitoring of workforce conditions and employment trends, as well as comprehensive self-reflection. To address this gap in the urban forestry profession, we studied municipal employees whose primary responsibilities directly involve planning, managing, and implementing urban trees and greenspaces. The purpose was to determine who is managing urban forests, and if the professional identity of urban foresters could be outlined. Survey topics included usage of professional support mechanisms such as certifications, conferences, and memberships. Less than half of respondents were arborists or urban foresters. Over half (55 %) of respondents were from locations that were being managed by non-tree professionals such as public administrators, civil engineers, landscape architects, and urban planners. This group had low rates of participation in tree-centric education, certifications, conferences, or memberships, suggesting that urban forest expertise may not be their priority. A regression analysis showed a distinction in the usage of professional support mechanisms between urban foresters and all other professionals, including arborists. We identified the support mechanisms urban foresters use to define their professionalism in lieu of a certification tailored to them. Recommendations include creating mechanisms for non-tree professionals to develop tree-centric skills and knowledge, and creating a certification for urban foresters.

In the United States, universities offering degrees in urban forestry are challenged by low enrollment. Meanwhile, there is a lack of racial/ethnic, and gender diversity among U.S. urban forestry practitioners. Identifying factors that influence career choice could help inform recruitment efforts for urban forestry degree programs and the profession. We surveyed more than 1,000 undergraduate students enrolled in natural sciences courses at 18 U.S. universities to evaluate their career decision-making processes. Students were first asked about their previous knowledge of urban forestry before viewing an informational video and then asked about their impression of an urban forestry career afterwards. Responses indicated that personal interest and job satisfaction were the most important factors for these students when considering career paths, even more important than pay and prestige. Previous knowledge of urban forestry was very low, especially among suburban students. After viewing the video, favorable impressions of urban forestry increased slightly. Students from families with annual incomes greater than 150,000 USD showed less interest in urban forestry than other students. Overall, student perceptions were not influenced by gender, race/ethnicity, childhood residential setting, or socio-economic status, and no significant intrinsic barriers to interest were identified. This suggests urban forestry may appeal to a more diverse population than is currently represented in the profession and lack of awareness may be a significant obstacle to recruiting not only more students, but also more diverse students. Thus, the profession may need to promote its public image well beyond traditional forestry and natural resources programs to reach new audiences.

Despite serving as invasion gateways for non-native forest pests, urban forests are less well understood than natural forests. For example, only a fraction of communities in the USA and Canada have completed urban forest inventories, and most have been limited to street trees; sample-based inventories that provide valid community-wide estimates of urban forest composition are much rarer. As a proof of concept, we devised a three-step approach to model urban tree distributions regionally using available street tree and whole-community inventory data. We illustrate the approach for three tree genera – ash (Fraxinus spp.), maple (Acer spp.), and oak (Quercus spp.) – that are hosts for high-profile insect pests. The objective of the first step was to estimate, for communities with only street tree inventories, the proportion of the community’s total basal area (BA) in each host genus. Utilizing data from communities with paired street tree and whole-community inventories, we applied polynomial regression to estimate whole-community BA proportion per genus as a function of a community’s street tree BA proportion and its geographic location. The objective of the second step was to estimate per-genus BA proportions for communities in our prediction region (eastern and central USA) with no urban forest inventory. We used stochastic gradient boosting to predict these proportions as a function of environmental and other variables. In the third step, we developed a generalized additive model for estimating the total BA of a community as a function of its canopy cover, geographic location, and area. We then combined the outputs from the second and third steps to estimate ash, maple, and oak BA for the nearly 24,000 communities in our prediction region. By merging these estimates with similar information on natural forests, we can provide more complete representations of host distributions for pest risk modeling, spread modeling, and other applications.

We collected 151 urban forestry job postings and analyzed them to determine minimum qualifications and average advertised salary and to construct a career ladder for the profession. We also interviewed 17 new hires who filled a cross-section of those positions and compared their qualifications and duties with job posting descriptions. Postings revealed a career ladder with two tracks: one requiring 4-year education and the other accepting experience in lieu of education. The ISA Certified Arborist credential was required by 45% of postings while the ISA Municipal Specialist was required by none. We found almost no entry-level positions in urban forestry. This suggests that students exiting 4-year degree programs will likely compete against far more experienced professionals for these positions. Experience as an arborist was accepted in lieu of education as an urban forester in about half of positions. However, a degree was required to reach the highest paying positions. Most employers (75%) were governments, especially local governments (63%).

Trees in residential neighborhoods and communities provide benefits for homeowners that are capitalized into residential property values. In this paper, we collected data from hedonic property value studies and merged these data with ancillary spatial data describing forest and socio-economic characteristics surrounding each study area to conduct a meta-analysis of the impact of tree canopy cover on the value of residential properties. The meta-analysis suggests that property-level tree cover of about 30% and county-level tree cover of about 38% maximize the implicit price of tree cover in property values. Currently, tree cover in the original study areas was about 14%, on average, around or near study properties. The empirical results, therefore suggest under investment of tree cover on private property from the perspective of individual property owners and from a societal perspective. The findings also have implications for community forest programs regarding planting trees and protection of mature trees to address potential changes in tree abundance, species diversity and stand age due to development and climate change.

The conversion of unmanaged forest land to homesites dominated by managed turfgrass lawns continues to increase and has large potential impacts on biogeochemical cycling. The conversion process from forest into mowed turfgrass involves a major disturbance to soil properties and shift in ecological conditions, which could affect soil physical, chemical and biological properties, including carbon sequestration. We conducted a study on 64 residential properties, ranging from 5 to 52 years since development, to compare soil carbon content, bulk density, temperature, and moisture, between lawns and the surrounding forests from which they were converted. Homeowners were surveyed on lawn management practices and environmental attitudes, and the relationships between these and soil properties were investigated. Soil bulk density was significantly higher in the upper 10 cm of lawns compared to adjacent forest (35% higher at 0–5 cm and 15.6% higher at 5–10 cm). Total soil C content to 30 cm of lawn (6.5 kg C m−2) and forest (7.1 kg C m−2) marginally differed (p = 0.08), and lawns contained significantly greater C (0.010 g C cm−3) than forests (0.007 g C cm−3) at the 20–30 cm soil depth (p = 0.0137). In the lawns, there was a positive relationship between time since development and surface (0–5 cm) C concentration (p = 0.04), but a negative relationship at 20–30 cm (p = 0.03). Surface soils also exhibited a positive correlation between fertilization frequency and C (p = 0.0005) content. Lawn management intensity (fertilizer and pesticide use) increased with environmental commitment. Homeowners with a higher environmental commitment had lawns with greater soil carbon levels. Our results indicate that converting unmanaged Appalachian hardwood forest into managed, turfgrass-dominated residential landscapes may affect C depth distribution, but results in little change in total soil carbon sequestration in the upper 30 cm.

In the early 1940’s, during the early stages of the Manhattan Project (WWII), of rural communities in Anderson County, Tennessee was rapidly converted into laboratory facilities and the city of Oak Ridge. The environment that became Oak Ridge experienced not only pollutants from the laboratory activities, but also alterations from the land-use change from rural to urban areas. Therefore, a study was conducted to determine the impacts of land-use change from rural to urban area on 1) street tree diversity and performance; and 2) the biological, chemical and physical properties, and nutrient dynamics of street tree ecosystem soils. There were a total of 607 street trees, composed of 37 different species, on the five main roadways in Oak Ridge, Tennessee. The street tree inventory revealed that the street tree ecosystems had a high relative abundance of Acer rubrum (21.91%) and Pyrus calleryana (19.93%). Chemical, rather than physical, soil and site properties in street tree ecosystems had the greatest impact on street tree performance. Soils differed street by street in their biological, chemical, and physical properties but were not influenced by traffic rates. There were also differences in soil microbial biomass carbon (MBC) during the winter on streets based on their diversity of trees; however, the most diverse street was among the lowest in soil microbial biomass. Seasonally, the winter proved to have not only greater amounts of soil microbial biomass carbon and nitrogen (MBN), but significantly less extractable organic carbon (EOC) and nitrogen (EON) and total labile carbon (TLC) than that in the spring. Overall, this study provided insights into the post urbanization impacts on the street trees, soils, sites, and nutrient dynamics within street tree ecosystems of Oak Ridge.

Urbanization degrades soil by surface soil removal and subsoil compaction. Subsoiling and organic matter incorporation offer potential to increase soil carbon (C) storage over time. We evaluated the effects of urban land development practices and post-development soil rehabilitation on soil C pools and microbial biomass carbon (MBC). In 2007, four treatments [typical development practice (A horizon removed, subsoil compacted, and A horizon soil partially replaced), enhanced topsoil (same as typical practice plus tillage), profile rebuilding (compost incorporation to 60-cm depth in subsoil; A horizon soil partially replaced plus tillage), and undisturbed soil] were applied to 24 plots in Virginia, USA. In 2011, soil C pools and MBC were measured at 0–5, 5–10 and 15–30 cm depths. In surface soils, undisturbed soils had greater total soil C (12.10 and 7.73 Mg C ha−1 at 0–5 and 5–10 cm depths, respectively) than the three practices where A horizon soils were disturbed. However, profile rebuilding had higher total soil C (6.12 Mg C ha−1) and larger available and aggregate-protected C pools (1.59 and 2.04 Mg C ha−1, respectively) at 15–30 cm depth than other treatments, including undisturbed. In surface soils, MBC ranged from 185.3 to 287.3 mg C kg−1 soil among all practices. At the 15–30 cm soil depth, profile rebuilding had the greatest MBC (149.5 mg C kg−1 soil). Total soil C, available, aggregate-protected and mineral-bound C pools had positive relationships with MBC at the 15–30 cm depth (r = 0.85, 0.71, 0.77, and 0.69, respectively). We found typical land development practices led to soil C loss during construction processes even when topsoil is replaced. Soil rehabilitation that includes compost additions and subsoiling has potential to increase soil C storage below the surface horizons.

We measured soil surface CO2 efflux (F s) in loblolly pine stands (Pinus taeda L.) located on the Virginia Piedmont (VA) and South Carolina Coastal Plain (SC) in efforts to assess the impact climate, productivity, and cultural practices have on F s in the managed loblolly pine ecosystem. The effect of stand age on F s was examined using a replicated chronosequence approach in which stands ranging from 1 to 25 years since planting were investigated. Soil CO2 efflux was measured on both VA and SC sites for over a year using a closed dynamic system. Multiple linear regression was used to evaluate F s correlates and examine the relationship between candidate explanatory variables and F s. Soil temperature (top 10 cm) was the major correlate with F s on both locations. We observed a positive age effect on F s in VA stands and no relationship between age and F s in SC stands. Annual soil C efflux declined with stand age in SC due to both reductions in soil temperatures as crown closure occurs and a diminishing heterotrophic C substrate pool. Annual estimated efflux ranges from 16.7 to 13.2 Mg C ha−1 for 1 and 20-year-old stands, respectively. In contrast, annual soil C efflux increased with age in VA stands as a result of the positive relationship between stand age and F s, which appears to be related to an increase in the contribution of root respiration to total F s over time. In VA stands, efflux estimates range from 7.6 to 12.3 Mg C ha−1 for 1 and 20-year-old stands, respectively. These results demonstrate the need to further consider the impact forest management and within-region variability have on soil C efflux over time when estimating C budgets.

Soil CO2 efflux resulting from microbial and root respiration is a major component of the forest C cycle. In this investigation, we examined in detail how soil CO2 efflux differs both spatially and temporally with respect to stand age for loblolly pine (Pinus taeda L.) plantations on the Virginia Piedmont. Throughout a 12-month period, efflux rates were measured both near the base of trees and midway between planting rows in stands of four age classes. Mean soil CO2 efflux rates measured during the 12-month study were 1.72, 2.58, 2.84, and 2.90 μmol/m2/s for 1- to 2-year-old, 4- to 6-year-old, 8- to 12-year-old, and 20- to 25-year-old stands, respectively. Time series analysis revealed that stand age had a significant effect on soil CO2 efflux rate. Additionally, mean efflux rates were consistently higher near the tree and time series analysis revealed that measurement position had a significant effect on soil CO2 efflux rate. Mean soil CO2 efflux rates, by position, for the 12-month study were 2.72 and 2.28 μmol/m2/s for the near and away measurement positions, respectively. Regression analysis was used to examine the influence of soil and climatic factors on seasonal changes in soil CO2 efflux. The most influential factors affecting soil CO2 efflux during the 12-month study were soil temperature, soil moisture, stand age, and measurement position. We believe respiring roots significantly influence soil CO2 efflux of plantation loblolly pine and account for differences observed between stands of different ages as well as spatial differences observed within a given stand.
