“…i-Tree Eco (formerly called UFORE, Urban Forest Effects Model) is designed to utilize standardized field data from sample plots or complete inventories, together with local hourly air pollution and meteorological data to analyze a detailed characterization of urban forest structure and quantify numerous ecological services for cities [25]. The i-Tree model has been widely used in case studies across the world to assess total ecosystem services for whole research areas without stratification or to compare one single stratum within a research area [50][51][52][53][54]. This research represents an innovative application of i-Tree Eco, using pre-stratified random sample plots created within the four types of urban green spaces to reveal the various characterizations of diverse types of urban green spaces in Luohe.…”

Urban green spaces play a crucial role in maintaining urban ecosystem sustainability by providing numerous ecosystem services. How to quantify and evaluate the ecological benefits and services of urban green spaces remains a hot topic currently, while the evaluation is barely applied or implemented in urban design and planning. In this study, super-high-resolution aerial images were used to acquire the spatial distribution of urban green spaces; a modified pre-stratified random sampling method was applied to obtain the vegetation information of the four types of urban green spaces in Luohe, a common plain city in China; and i-Tree Eco model was further used to assess the vegetation structure and various ecosystem services including air quality improvement, rainfall interception, carbon storage, and sequestration provided by four types of urban green spaces. The modeling results reveal that there were about 1,006,251 trees in this area. In 2013, all the trees in these green spaces could store about 54,329 t of carbon, sequester about 4973 t of gross carbon, remove 92 t of air pollutants, and avoid 122,637 m 3 of runoff. The study illustrates an innovative method to reveal different types of urban green spaces with distinct ecosystem service productivity capacity to better understand their various roles in regulating the urban environment. The results could be used to assist urban planners and policymakers to optimize urban green space structure and composition to maximize ecosystem services provision.Sustainability 2020, 12, 1630 2 of 16 of various vegetation communities within the urban area [24][25][26][27][28][29], while there are few studies that analyze variations in types and functions of urban green spaces at finer scales [1,22,30]. Urban green spaces are divided into several types, reflecting the different needs that these spaces meet, which could further affect the different ecosystem services provision. The capacity of various green spaces ecosystem services provision is context-specific and different depending on their type and size [31,32]. Various types of urban green spaces such as public parks, road belt green space, wetland, and private gardens are extremely heterogeneous with different vegetation communities and diversities reflecting diverse social needs and personal preferences that further influence eco-function value provision [33].In China, spatially heterogeneous urban green spaces are classified into four main types, which are public parks, protective green spaces, square green spaces, and attached green spaces by individual location and function across urban area based on Standard for Classification of Urban Green Space (CJJ/T85-2017), which was released by Ministry of Housing and Urban-Rural Development of P.R.C. in 2017. Different social needs and ecological values that are driven by landowners' preferences and function-oriented design bring various types of urban green spaces [34]. Diverse vegetation preferences and differing management and maintenance practices reflect human-oriented d...

This report constitutes the third full report of annualized inventory on Ohio forest land and summarizes field data collected from 2011 through 2016. Ohio has 8.0 million acres of forest land containing 103 tree species and 50 forest types. Net cubic-foot and sawtimber volumes continued to increase, as did the area occupied by large diameter stands. Growing-stock volume remained stable overall, though it decreased 3 percent on private land since 2006. The net-growth-to-harvest-removals ratio dropped from 2.3:1 in 2011 to 1.6:1 in 2016. Invasive insects have had a substantial impact on Ohio's forests, particularly for ash species. Additional information on land-use change, fragmentation, ownership, forest composition, structure, age, carbon stocks, regeneration, invasive plants, insect pests, and the possible future of Ohio's forests is also presented. Sets of supplemental tables are available online at https://doi.org/10.2737/NRS-RB-118 and contain: 1) tables that summarize quality assurance and 2) a core set of tabular estimates for a variety of forest resources.Cover: Vinton County scene.

They are incredibly biodiverse, providing habitat for hundreds of species of plants and terrestrial wildlife. These areas also provide many recreational opportunities, improve water and air quality, and serve as a natural retreat for people, benefiting mental and physical health. The forests of Ohio also support a thriving forest products industry, which contributed over $26 billion to the State's economy and employed 122,000 people in 2015. Forests are clearly important for Ohio, and the data generated by the USDA Forest Service's Forest Inventory and Analysis program provide the basis for understanding how they are changing and how we can sustain them for future generations.This and previous reports show that the proportion of Ohio in forest cover has remained at 30 percent since 1991, after increasing steadily since the low point of about 10 percent forest cover in 1910. Eighty-five percent of the forest land in Ohio is privately owned, meaning private landowners are critical to the continued health of our forests. While only 12 percent of landowners owning 10 or more acres have management plans for their forests and fewer than 20 percent have received forest management advice, these figures have improved significantly from previous reports. Additional encouraging findings from this report include the increase in the area of mature forests containing large trees and improvement in the quality of sawtimber.While Ohio's forests provide us with a wealth of ecological and economic services, they are faced with some key challenges, including fragmentation, reduced oak regeneration, and invasive species. New home production is increasing at a rate 4.5 times that of the population growth. Much of this construction is encroaching on forest...
