“…Bioproducts from poplars (propolis, flavonoids, bud extracts) have also various applications in medicine, health foods, cosmetics and plant disease control [146,147]. Poplar foliage and rameal wood are currently used as an inexpensive fodder during drought or as supplements to increase livestock reproductive capacity [148,149]. Litter fall from poplar buffers reaching adjacent cropping systems can contribute to improving soil fertility and food crop productivity [150].…”

Abstract:In temperate agricultural watersheds, the rehabilitation of tree vegetation in degraded riparian zones can provide many ecosystem services. This study evaluated ecosystem service provision potential following the conversion of non-managed herbaceous buffers to hybrid poplar (Populus spp.) buffers in three watersheds (555-771 km 2 ) of southern Québec (Canada), with contrasting agricultural land uses. To extrapolate services at the watershed level, total stream length where hybrid poplars could be established was calculated using GIS data from hydrological and land cover maps. After nine years, a 100% replacement of herbaceous buffers by hybrid poplar buffers along farm streams could lead to the production of 5280-76,151 tons of whole tree (stems + branches) biomass, which could heat 0.5-6.5 ha of greenhouses for nine years, with the potential of displacing 2-29 million litres of fuel oil. Alternatively, the production of 3887-56,135 tons of stem biomass (fuelwood) could heat 55-794 new farmhouses or 40-577 old farmhouses for nine years. Producing fuelwood in buffers rather than in farm woodlots could create forest conservation opportunities on 300-4553 ha. Replacing all herbaceous buffers by poplar buffers could provide potential storage of 2984-42,132 t C, 29-442 t N and 3-56 t P in plant biomass, if woody biomass is not harvested. The greatest potential for services provision was in the Pike River watershed where agriculture is the dominant land use. A review of the potential services of poplar buffers is made, and guidelines for managing services and disservices are provided.

In the province of Québec, approximately 12 000 ha of fast-growing poplar plantations are managed by industrials, while small private landowners have planted only 1000 ha. Most of these poplar plantations are established on clearcut forest sites (approx. 11 000 ha). What are the yields of these hybrid poplar plantations? In this article, available yield data are presented and discussed in the context of a sustainable forest zoning management system. In southern Québec, three factors are highly correlated to yield for clones of various parentages: NO 3 supply rate in riparian soils, elevation (or climate) and soil P availability in abandoned farmland soils. Many Québec forest sites, particularly in the boreal shield ecozone, have acidic soils and harsh climate, with low mineralization rates. They generally cannot fulfill the very high nutrient requirements of hybrid poplars. Within a forest zoning management system, hybrid poplar plantations and agroforestry should be located in priority in southern Québec landscapes, with low remaining natural forest cover, and where intensive agriculture is the dominant land-use. This strategy will increase biodiversity and the provision of ecosystem services. Elsewhere, intensive trembling aspen regeneration silviculture could be a sustainable alternative to forest conversion into hybrid poplar plantations.Key words: afforestation, agroforestry, forest conversion, intensive aspen silviculture, ecosystem services, biodiversity, biomass RÉSUMÉAu Québec, il existe approximativement 12 000 ha de plantations de peuplier hybride aménagés par l'industrie et 1000 ha aménagés par des propriétaires privés. La plupart de ces plantations (environ 11 000 ha) ont été aménagées sur des sites forestiers suite à une coupe totale. Quel est le rendement de ces plantations? Dans cet article, les données de rendement disponibles sont présentées et discutées dans une perspective de zonage d'aménagement forestier durable. Dans le sud du Québec, trois facteurs fortement corrélés au rendement de différents clones non apparentés ont été identifiés: le flux de NO 3 dans les sols riverains, l'altitude (climat) et le P disponible dans le sol des terres agricoles abandonnées. Plusieurs sites forestiers du Québec, particulièrement dans l' écozone du bouclier boréal, ont un sol acide, un climat rigoureux et un faible taux de minéralisation. Ces sites ne pourront pas satisfaire les exigences nutritionnelles élevées des peupliers hybrides. Dans une perspective de zonage d'aménagement forestier durable, les plantations et les systèmes agroforestiers de peuplier devraient, en priorité, être établis dans le sud du Québec dans les paysages d'agriculture intensive, là où le couvert forestier résiduel est faible. Cette stratégie permettra d'augmenter la biodiversité et la production de services écologiques. Ailleurs, la silviculture intensive du peuplier faux-tremble basée sur la régénération naturelle pourrait être une approche alternative et durable à la conversion de forêts en plantations de peuplier hybr...
