“…The results are in line with previous studies indicating that inorganic N output occurs predominantly as NO 3 -N rather than NH 4 -N and that most of the leached N from boreal clear-cut forests is organic N (Grip 1982;Lamontagne et al 2000;Löfgren et al 2009, Table 4). The increases in stream water NO 3 -N concentrations and loads in C34 could result from higher deposition loads due to the lack of N retention by tree canopy (Piirainen et al 2002), greater snow accumulation on clear-cut areas (Varhola et al 2010), reduced nutrient uptake by trees and understory vegetation (Piirainen et al 2002;Finér et al 2003;Palviainen et al 2004Palviainen et al , 2005Palviainen et al , 2007, and increased nitrification in the litter layer and soil (Paavolainen and Smolander 1998;Smolander et al 2000Smolander et al , 2001Piirainen et al 2007). NO 3 -N is poorly retained in the soil by sorption and can easily be leached to ground and surface waters after clear-cutting (Ahtiainen 1990;Rosén et al 1996;Kubin 1998;Kreutzweiser et al 2008).…”

The long-term impacts of current forest management methods on surface water quality in Fennoscandia are largely unexplored. We studied the long-term effects of clear-cutting and site preparation on runoff and the export of total nitrogen (total N), total organic nitrogen (TON), ammonium (NH 4 -N), nitrate (NO 3 -N), total phosphorus (total P), phosphate (PO 4 -P), total organic carbon, and suspended solids (SS) in three paired-catchments in Eastern Finland. Clear-cutting and soil preparation were carried out on 34 % (C34), 11 % (C11), and 8 % (C8) of the area of the treated catchments and wide buffer zones were left along the streams. Clear-cutting and soil preparation increased annual runoff and total N, TON, NO 3 -N, PO 4 -P, and SS loads, except for SS, only in C34. Runoff increased by 16 % and the annual exports of total N, TON, NO 3 -N, and PO 4 -P by 18, 12, 270, and 12 %, respectively, during the 14-year period after clear-cutting. SS export increased by 291 % in C34, 134 % in C11, and 16 % in C8 during the 14, 6, and 11-year periods after clear-cutting. In the C11 catchment, NO 3 -N export decreased by 12 %. The results indicate that while current forest management practices can increase the export of N, P and SS from boreal catchments for many years ([10 years), the increases are only significant when the area of clear cutting exceeds 30 % of catchment area.

Abstract:Changing and competing land use, where we make use of a growing share of resources, potentially undermines the capacity of forests to provide multiple functions such as timber, biodiversity, recreation and pasture lands. The governance challenge is thus to manage trade-offs between human needs and, at the same time, maintain the capacities of forests to provide us with these needs. Sweden provides a clear example of this kind of challenge. Traditionally, timber has been the most apparent contribution of the forest to Swedish national interests. However, due to competing land use, the identification of the wider role of forests in terms of multifunctionality has been recognized. Today, a number of functions, such as water quality and biodiversity together with cultural and social activities related to forests, are increasingly included as potential demands on forests in competition with traditional functions such as timber production. The challenge is thus related to trade-offs between different functions. How to balance the relationship and guide trade-offs between different functions of forests is, to a large extent, a matter of policy choice and the design of appropriate governance institutions and pro-active management activities. Based on perceptions among stakeholders on future competing demands and a literature review, the paper explore the multifunctionality of the Swedish forests and how it is affected by competing demands for land use; how multifunctionality is currently governed; and concludes by suggesting promising decision support methods to manage trade-offs between different functions.

“…DOM exports are large because peatlands are in close hydrological contact with receiving watercourses, peat C storage is large, organic matter decomposition is incomplete due to the anaerobic conditions, and the peat contains few compounds that can retain C such as iron and aluminium (Domisch et al 2000;Kalbitz et al 2000;Freeman et al 2001). In mineral soil sites, C that is leached from organic layer is effectively retained on iron-and aluminium-rich mineral soil layers even after disturbances such as clear-cutting and soil preparation (Piirainen et al 2007) and eventually a large proportion of organic matter they contain are mineralized into CO 2 . The amounts of TOC, DON and DOP in streams and lakes have been shown to be significantly related to soil type with higher TOC, DON and DOP export from peatland dominated catchments in comparison with forest dominated upland catchments (Willett et al 2004;Kortelainen et al 2006).…”

The majority of C, N and P in boreal lakes are in organic form. Organically bound nutrients are released through biodegradation or photodegradation which affects the water quality, eutrophication and greenhouse gas emissions of lakes. We tested whether open land-use data combined with land-use-specific export coefficients can be used to predict total organic carbon (TOC), dissolved organic nitrogen (DON) and dissolved organic phosphorus (DOP) loading and lake water concentrations. Using data from 12 lake catchments in eastern Finland, we found that land use and management of the catchment explained a substantial proportion of the variations in TOC (r 2 = 0.78), DON (r 2 = 0.55) and DOP (r 2 = 0.80) concentrations between lakes. The computation does not account for in-lake processes, which are reflected as mismatch between the predicted and observed concentrations. However, this simple practical approach is useful in ranking lakes according to their water quality. The results indicated that natural sources dominate TOC, DON and DOP exports; the background leachings accounted for 57-99 %, 48-96 % and 55-99 % of TOC, DON and DOP export, respectively. The proposed method has promise as a practical decision support tool for assessing the impacts of land use on water quality. The results showed that possibilities to control TOC, DON and DOP loading to surface waters are limited to catchments where the peatland proportion is low and anthropogenic sources significant.
