“…This resulted in few seedlings being established and hence reduced the power of the study to measure treatment effects on pine seedling recruitment. The estimated detection rate of small seedlings would have allowed measurement of treatment differences had seed-fall been higher, as was the case in the related study of Hancock et al (2009). Despite this, some supporting evidence for cattle impacts promoting new pine seedling establishment came from the within-forest plot, where seed-fall will have been much higher.…”

“…This might give impacts that were not only more pronounced but also longer-lasting, allowing more seasons of seed-fall to contribute to pine seedling recruitment. However, managers should also carefully compare the potential of management using cattle, against other approaches, like prescribed fire, well supported as a tool for promoting Scots pine regeneration (Hancock et al 2009). Such approaches may have cost and biodiversity advantages, depending on site constraints and objectives.…”

“…Seedlings which lacked paired needles were classed as 'year-one' seedlings (Carlisle and Brown 1968). The detection rate of seedlings, when using an identical search method, was measured by Hancock et al (2009) using dummy seedlings. These data were used to model seedling detection rate as a function of seedling size and vegetation openness.…”

It has been argued that large ungulates play a key role in natural forest dynamics, but in Britain, the largest native ungulates (aurochs and elk) are extinct. Cattle could have some similar effects, and are widely used, but rarely tested, for nature conservation management. Here, we test conservation management with cattle at a native Scots pine Pinus sylvestris forest in Scotland. Our hypotheses were that cattle impacts would (a) increase the abundance of an understorey shrub of conservation importance, bilberry Vaccinium myrtillus; and (b) increase Scots pine seedling establishment. Two cattle trials were established, one for each objective, based on a 14-ha plot within the forest, and a 6.1-ha plot at the forest edge. Cattle were introduced for 2 months to both plots, giving an approximately 100-to 150-fold increase in ungulate biomass per hectare when compared to background deer abundance. The ground layer vegetation in both treatment and matched control plots was monitored before and after treatment, and subsequently over a 4-year period. At the within-forest trial, bilberry percent-cover, 4 years after treatment, was 1.9 times higher in the cattle area than in the control (95% confidence limits 1.6-2.3). Bilberry percentcover increases were directly related to the degree of trampling impact on heather Calluna vulgaris, as recorded immediately after the trial. At the forest-edge trial, there were vegetation changes in the cattle plot that were considered favourable to pine seedling establishment: reduced moss/litter depth and vegetation percent-cover, and increased ground-level light incidence. However, too few new pine seedlings were found for formal analysis, partly due to unexpectedly low seed-fall. Nevertheless, the potential for cattle to create conditions that would subsequently promote pine regeneration was illustrated by the observation of large numbers of new, young pine seedlings at the within-forest cattle plot. We recommend that managers and researchers collaborate to develop further trials like the ones reported here, to give an improved understanding of the conditions under which cattle can yield nature conservation benefits in woodlands.

“…Meanwhile, the implementation of empirical results to the model will increase the potential of its practical application, especially in prescribed burning scenario. The following notion was also confirmed by empirical enhancement of Scots pine regeneration in Scotland (Hancock et al, 2009). …”

This paper presents the perspectives of FORKOME model use regarding the simulation of fire and its impact on forest stands. The calculation of probability of forest fires and predicting its effect on forest stands are analysed as well. The model is supposed to examine the impact of fires on pine stands, which ultimately leads to a decline in the viability of those trees. As a result of fire activity, there were determined the following categories of trees -undamaged, slightly damaged, heavily damaged and destroyed. Moreover, by conducting simulations on forests with Scots pine (Pinus sylvestris L.), there were demonstrated the possibilities of FORKOME model practical application. Simulation shows the possibility of the model to predict the fire damage in a particular year and the perspective of a stand development, taking into account climate change and its influence on the frequency of fires. Prospects and directions of further developments of the model concerning simulation of fire in forest stands were discussed as well.

“…Through simulations, we demonstrated that the use of prescribed burning is much more effective than the removal of spruce. It has been confirmed empirically that prescribed burning enhances the regeneration of Scots pine in Scotland (Hancock et al 2009). Linder et al (1997) suggested that management plans for forest reserves should include management practices that maintain or mimic the natural disturbance regimes in a certain way.…”

This paper presents a modelling study on the forest dynamics in Helgedomen Nature Reserve (HNR) in Sweden. The main components of the forest transitions that occurred between 1930 and 2010 were described. The gradual conversion of Scots pine (Pinus sylvestris L.) dominated stands into stands with a high proportion of Norway spruce (Picea abies [L.] Karst.) was observed. Next, the capabilities of the modelling system (FORKOME) in predicting the future development of forests in the reserve were tested. The model was validated by simulating forest development from 1930 to 2010, and then it was applied to project the future development of forests in the reserve. Scenarios generated in the forecasting component of the model were (1) no intervention, (2) removal of spruce, and (3) prescribed burning. The FORKOME model was able to predict possible alterations of species composition, stem volume, total biomass in the next 100 years under these three scenarios. We argue that in the absence of natural fires, the active management of small reserves is required in order to maintain the major natural values. Prescribed burning is more effective than spruce removal for maintaining the pine-dominated character of the stands and to sustain the conservation value of the reserve.
