“…There are currently no measurements of PM10 deposition in the park, and this analysis uses figures from the UK, where high variation in PM10 deposition rates was found (Broadmeadow et al 1998). Second, there is uncertainty regarding the reduction in ambient PM10 concentration as a consequence of air filtration in the park (see also Bealey et al 2007). In comparison, a study in the UK (Willis et al 2003) assumed that health benefits from air filtration by forests only occur at short distances (<1 km) from the forest.…”

ABSTRACT. Eliciting the economic benefits provided by protected areas is important in order to ensure that they are properly considered in policy and decision making. There are relatively few studies that provide a comprehensive overview of the economic benefits provided by European forest ecosystems, in spite of the large share of forests in the protected area system in most countries. An economic valuation of the ecosystem services supplied by the Hoge Veluwe forest in the Netherlands is presented. The Hoge Veluwe forest is one of the largest and most well-known protected areas in the country. The services included in the study are wood production, supply of game, groundwater recharge, carbon sequestration, air filtration, recreation, and nature conservation. A conservative estimate of the total economic benefits generated by the forest is around 2000 Euro/ha/year, which is more than three times higher than the per hectare-value generated by nearby agricultural land. The study provides an analysis of the economic value of eight ecosystem services, discusses the uncertainties of the value estimates, and examines the implications for financing protected area management.

“…The most recognized benefits, stemming from urban forest ecological services (McPherson et al 2005), are: rainwater retention (Chen and Jim 2008), flood regulation (Sanders 1986), water quality protection (Xiao et al 1998), moderation of the urban climate (Lafortezza et al 2009;Hamada and Ohta 2010;Armson et al 2012) and air pollution reduction (Brack 2002;Bealey et al 2007;McDonald et al 2007;Zupancic et al 2015). In terms of hydrological role, forest ecosystems in urban environments represent qualitative and quantitative filter for rainwater (Bellot and Escarre 1998).…”

Urban forests provide important ecosystem services. In terms of hydrological benefits, forest ecosystems in urban environments represent qualitative and quantitative filter for rainwater. We quantified the canopy interception in relation to urban forest stand structure and rainfall intensity in an urban transect of the mixed (upland) forest in the city centre, towards a riparian pine forest and a floodplain hardwood forest in the City of Ljubljana, Slovenia. Bulk precipitation in open areas and throughfall were measured with fixed rainfall collectors in each forest. Stemflow was estimated from a review of relevant literature. We found that canopy interception in selected urban forests was mainly affected by tree species composition and other stand structure variables, such as canopy cover and tree dimensions. Average annual canopy interception was highest in the mixed forest (18.0% of bulk precipitation), while the riparian pine forest had the lowest level (3.9% of bulk precipitation) and the floodplain hardwood forest had the intermediate level for interception (7.1% of bulk precipitation). The mixed forest exhibited the stand structure factors that contributed to the highest canopy interception among the studied forests: high assemblage of dominant coniferous trees, denser canopy cover and the highest growing stock. Furthermore, rainfall intensity has proven to be an important factor for the seasonal partitioning (comparing the leafed and leafless period) of canopy interception. A better understanding of precipitation interception processes in urban forests is needed to assist urban forest managing and planning, aiming at maximizing canopy interception for the mitigation of stormwater runoff and flooding in urbanized watershed.

“…Roadside tree canopies may adjust air quality through changing air dispersion as well as by capturing air pollutants. Recent studies have found that a street tree canopy has a positive or negative effect on air quality at the pedestrian level [37,38]. The positive effect is the obstacle posed by plants to air flow, reducing air exchange especially in the vertical direction and increasing air pollutant concentrations.…”

Particulate matter is a serious source of air pollution in urban areas, where it exerts adverse effects on human health. This article focuses on the study of subduction of shelterbelts for atmospheric particulates. The results suggest that (1) the PM mass concentration is higher in the morning or both morning and noon inside the shelterbelts and lower mass concentrations at other times; (2) the particle mass concentration inside shelterbelt is higher than outside; (3) the particle interception efficiency of the two forest belts over the three months in descending order was PM10 > PM1 > PM2.5; and (4) the two shelterbelts captured air pollutants at rates of 1496.285 and 909.075 kg/month and the major atmospheric pollutant in Beijing city is PM10. Future research directions are to study PM mass concentration variation of shelterbelt with different tree species and different configuration.
