Large-scale global reforestation goals have been proposed to help mitigate climate change and provide other ecosystem services. To explore potential in the United States, we used GIS analyses, surveys of nursery managers foresters, literature synthesis assess opportunities challenges associated with meeting goals. We considered a scenario where 26 million hectares (64 acres) natural agricultural lands are reforested by 2040 30 billion trees at an estimated cost $33 ($24–$53) USD. Cost per...
Successful establishment of Pinus ponderosa seedlings in the southwestern United States is often limited by stressful and harsh site conditions related to drought severity severe disturbances such as wildfire mining operations. Seedling quality has an important influence on outplanting performance, but nursery practices that typically employ optimal growing environments may also be limiting seedling morphological physiological performance sites. To address this, a study was established test...
México's incredibly diverse forests are designated by federal regulations as "multipurpose" and managed for the benefit economic welfare of local communities. In addition to traditional wood products, provide grazing lands, nonwood forest fuelwood, ecosystem services. Unfortunately, growing populations structure community enterprises placing increasing stress on resources. Furthermore, illegal harvesting, selective logging, routine burning forage production, unsuccessful reforestation...
In the western US, quaking aspen (Populus tremuloides Michx.) regenerates primarily by root suckers after disturbances such as low to moderate severity fires. Planting seedlings grown from seed may provide a mechanism improve restoration success and genetic diversity on severely disturbed sites. However, few studies have examined use of container-grown for purposes both outplanting nursery production perspective. Thus, purpose this novel study was examine how alterations in irrigation levels...
In developing countries, tree seedlings are often produced in polybags filled with mixtures of locally available materials. Seedling growth and quality can be affected by the type amount these substrates used mixture. Differences seedling also significantly when fertilization is employed during nursery growing period. this study, we assessed effects five different media two regimes on growth, morphology early post-planting response to drought Eucalyptus benthamii (Maiden & Cambage)...
Anthropogenic activity has caused persistent and prominent losses of forest cover in dry tropical forests. Natural regeneration trees grazed areas often fails due to lack seed sources consumption by ungulates. To address this, the effective restoration such sites requires fencing outplanting nursery-grown seedlings. In degraded, forests Hawaii, USA, an additional challenge native is introduced kikuyu grass (Cenchrus clandestinus). This invasive, rapidly growing rhizomatous plant forms deep,...
Quercus spp. (oaks) are generally intermediate in shade tolerance, yet there is large variation within the genus tolerance and plasticity response to varying resource availability. Ecophysiological knowledge specific semi-evergreen from subtropical maritime forests lacking relative temperate deciduous oaks. We studied influence of light availability plant competition on leaf physiology performance virginiana a barrier island along US southern Atlantic coast. Seedlings were underplanted pine...
We investigated early survival, growth, and carbon isotope discrimination of ponderosa pine (Pinus Lawson & C. var. scopulorum Engelm.) seedlings from different provenances using common gardens across an elevational gradient in order to examine the potential for adaptation extreme environments constraints artificial regeneration. Twenty-one a range elevations Arizona New Mexico were planted three gardens: high-elevation meadow aspen-mixed conifer forest, mid-elevation low-elevation...
Herbivory and competition during the regeneration phase influence forest successional dynamics. We demonstrated importance of using Target Plant Concept to identify overcome site limiting factors for subtropical maritime restoration associated with deer browsing competition. Quercus virginiana Mill. (live oak) bareroot seedlings were planted into clearcuts along US Southern Atlantic coast different treatment combinations herbivory control (fenced or non-fenced) against white-tailed...
Aspen forests are threatened by the impacts of a changing climate and showing large-scale mortality with meager natural regeneration to restore these loses. Therefore, there is an increasing demand for high-quality aspen seedlings assist forest restoration efforts. Nursery cultural practices can be used alter seedling traits improve adaptability dry planting conditions. In this study, effects container size (SC10 D30; 158 490 mL, respectively) nursery irrigation treatment (high low...
Haiti has suffered great losses from deforestation, with little forest cover remaining today. Current reforestation efforts focus on seedling quantity rather than quality. This study examined limitations to the production of high-quality seedlings endemic Hispaniolan pine (Pinus occidentalis Swartz). Recognizing importance applying sustainable development principles restoration, effects growing media and container types growth were evaluated goal developing a propagation protocol produce...
Reforestation is needed globally to help restore degraded sites, combat desertification, protect watersheds, and provide forest products. This involves planting tree seedlings grown in local nurseries, but technologies produce quality are lacking developing countries. Modern nursery containers used propagate have internal-surface barriers (ribs or ridges) side-slits prevent root spiraling. These cost prohibitive unavailable countries so polybags (plastic bags) more commonly used, despite...
Herbivory is a common forest regeneration challenge across ecosystems. While fencing effectively reduces animal browse damage, it can be impractical. Tree shelters are an alternative restoration tool to protect seedlings from herbivory that may also provide favorable microclimate. Yet, responses tree often vary among species, environmental conditions, and shelter specifications. To restore the once dominant Quercus virginiana (live oak) its associated conservation values subtropical U.S....
Ponderosa pine (Pinus ponderosa Lawson & C. var. scopulorum Engelm.) forests of the southwestern US are threatened by climate change and deforestation. Information about geographic patterns provenance variation in budburst phenology is needed to make decisions selecting seed sources for future planting. In this study, seedlings was examined using common garden studies. Seedlings from 21 provenances, representing an elevational gradient Arizona New Mexico, were planted July 2018 at a...
Abstract We examined the microsite characteristics of 6,048 Douglas-fir seedlings at three regeneration sites in Washington state. Our objective was to determine that were most influential on seedling growth change over time. analyzed influences both individually and concert with one another through regression-based techniques. Microsite parameters included soil impedance, topographic, physical parameter measurements recorded each seedling's location. Akaike's information criterion (AIC)...
