“…Canopy interception of precipitation is one of the most important (Li et al 2016) hydrological processes in forest ecosystems (Brauman et al 2010). The results of this study suggest that canopy precipitation partitioning in selected urban forests is strongly influenced by tree species composition, canopy cover and growing stock (i.e., tree dimensions) as well as rainfall spatial distribution and intensity.…”

“…Those are all stand structure variables which contribute to higher canopy interception (Toba and Ohta 2005;Dietz et al 2006;Vilhar 2016). Conifers tend to have greater interception capacity than deciduous trees (Inkiläinen et al 2013) and large trees with considerable canopy surface area can decrease throughfall by intercepting a substantial fraction of bulk precipitation (Brauman et al 2010). In an urban park in the city of Ljubljana, coniferous tree species (Pinus sylvestris) exhibited evidently higher canopy interception (51-65% of bulk precipitation) compared to deciduous tree (Betula pendula; 23- Fig.…”

“…Weather conditions vary at small and large scales (Brauman et al 2010). The precipitation amount can change significantly over short distances due to complex topography (Diodato 2005;Vilhar 2010;Vilhar et al 2017), contributing to considerably different microclimate conditions (Crockford and Richardson 2000;Tetzlaff and Uhlenbrook 2005).…”

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.

“…In Mexico, landowners participating in the watershed investment program receive *US$40 ha year -1 to conserve montane cloud forest because program designers assumed that dry-season cloudwater interception represents an important contribution to streamflow (Muñoz-Piña et al 2008). Payments are contingent on the extent of forest cover and not on forest condition, even though cloud deposition varies with canopy leaf area (Brauman et al 2010;Ponette-González et al 2010). Managed agroforests or young forests with low leaf areas may have insufficient surface area to capture and deliver cloudwater ([100 % throughfall) to downstream water users (Fig.…”

Watershed investment programs frequently use land cover as a proxy for water-based ecosystem services, an approach based on assumed relationships between land cover and hydrologic outcomes. Water flows are rarely quantified, and unanticipated results are common, suggesting land cover alone is not a reliable proxy for water services. We argue that managing key hydrologic fluxes at the site of intervention is more effective than promoting particular land-cover types. Moving beyond land cover proxies to a focus on hydrologic fluxes requires that programs (1) identify the specific water service of interest and associated hydrologic flux; (2) account for structural and ecological characteristics of the relevant land cover; and, (3) determine key mediators of the target hydrologic flux. Using examples from the tropics, we illustrate how this conceptual framework can clarify interventions with a higher probability of delivering desired water services than with land cover as a proxy.

“…We employ an experimental approach to provide insight into potentially useful tools for achieving culturally and financially acceptable restoration targets [62]. An acceptable and feasible target in this case may be a system that conserves some biodiversity, notably by improving habitat for the critically endangered C. Hawaiiensis, while providing locally desired ecosystem services [63], such as enhanced groundwater recharge [64] and opportunities for collecting native plants for traditional use [65].…”

Ecological restoration is an increasingly important component of sustainable land management. We explore potential facilitative relationships for enhancing the costeffectiveness of restoring native forest understory, focusing on two factors: (1) overstory shade and (2) possible facilitation by a fern (Dryopteris wallichiana), one of few native colonists of pasture in our montane Hawaiˈi study system. We planted 720 understory tree seedlings and over 4000 seeds of six species under six planting treatments: a full factorial combination of low, medium and high light, situating plantings in either the presence or absence of a mature fern. After three years, 75% of outplanted seedlings survived. Seedling survivorship was significantly higher in the presence of a fern (79% vs. 71% without a fern) and in medium and low light conditions (81% vs. 64% in high light). Relative height was highest at low to medium light levels. After 2.2 years, 2.8% of the planted seeds germinated. We observed no significant differences in seed germination relative to light level or fern presence. Analyzing several approaches, we found nursery germination of seeds followed by outplanting ca. 20% less costly than direct seeding in the field. This study opens new questions about facilitation mechanisms that have the potential to increase the extent and effectiveness of restoration efforts.
