Potential Use

Abstract This study evaluates the potential usefulness and toxicity of applying quadrivalent selenium (selenite ion) to the soil to discourage white-tailed deer from browsing conifer seedlings. After absorption by the root system and internal transport, organoselenium compounds are volatilizedby the foliage, and the characteristic garlic odor is hypothesized to protect coniferous tree seedlings from browsing damage. Results indicate that either 5, 17, or 24 months after treatment, selenized white spruce seedlings did not show significantly different deer-browsing damage from controlseedlings when deer numbers were high. Five and seventeen months after treatment, selenium had not leached but had accumulated in the top soil. Large-scale application of selenium may represent a potential environmental risk, hence we do not recommend use of selenite ion to prevent damagefrom deer-browsing of white spruce seedlings. North.

Heavy Damage

In the region of Rýchory (KRNAP – the Krkonoše National Park), effects of roe deer and red deer browsing on the condition and development and natural and artificial regeneration of stands was studied in 2003–2004. Winter and summer browsing were observed in 14 couples of plots (always one with mechanical protection, the second without the protection) and in one control couple in a wintering preserve for red deer. In both years, winter browsing predominated in the region and thus, it is possible to suppose that roe deer was the main browser. As for natural regeneration, silver fir (26% in winter 2003), rowan (36% in winter 2003) and sycamore maple (26% in winter 2004) were the most damaged species. In artificial regeneration, silver fir damage predominated (68% in winter 2003). In the wintering game preserve with the high winter concentration of red deer, damage to all trees exceeded 40% and heavy damage showed also species slightly damaged out of the preserve such as spruce (63%) and beech (75%). Artificial regeneration was damaged more markedly than natural regeneration in all terms of monitoring. The percentage of browsing damage increased with the distance of the additional feeding device.

Shoot Mass

Ash from biofuels and nitrogen fertilizer are increasingly being used as soil amendments. While this can increase tree growth, it can also increase mammalian grazing and competition with vegetation. We applied moderate amounts (1.5 t ha<sup>-1</sup> y<sup>-1</sup>) of ash and 74 kg N ha<sup>-1</sup> y<sup>-1</sup> of urea in each of two years to a well-drained site in southeastern Manitoba, planted with <i>Pinus banksiana</i>. Subplots received deer browsing and/or vegetation control. The ash resulted in an increase in pH in the upper 15m of mineral soil from ca. 5.7 to 6.6, and the urea created short-term spikes in soil inorganic N (NH<sub>4</sub> and NO<sub>3</sub>) levels. Urea combined with ash significantly increased seedling relative growth rates in the first two years, with seedlings being largest with urea, with or without ash. However, by the fourth year seedling growth and size did not differ between the amendments. Urea application increased browsing damage to 91 %, but only when vegetation was mowed. Browsing guards resulted in seedlings having 1.6 times greater shoot mass by the end of the fourth growing season. These results suggest that on sandy soils in the dry region of central Canada, <i>P. banksiana</i> may get little benefit from ash applications.

Browsing cascades have strong implications for biodiversity conservation and fire management. The associational resistance and associational susceptibility hypotheses suggest different mechanisms. We tested the veracity of these two hypotheses by using small dry eucalypt forest and woodland trees. At 67 sites, we measured the height of the browse line and estimated the proportion of foliage remaining below it for all adult individuals of small trees within a 50 × 50 m area, recorded scat numbers, browsing damage to tree seedlings by species and environmental data. The 110–130-cm browse line, and strong relationships between macropod scat numbers and the remaining foliage below the browse line, suggested that Bennetts wallabies (Macropus rufogriseus Shaw) were the main cause of umbrella-shaped trees. The browsers preferred Exocarpos cupressiformis Labill. and Bursaria spinosa Cav. At the other extreme, adult Acacia dealbata Link suffered no browsing damage. All species were browsed as seedlings. Associational resistance occurred in some species and associational susceptibility in others, with the degree of difference in palatability between alternative sources of browse possibly resolving this apparent contradiction. Low browsing pressure is likely to cause woody thickening, an increase in fire hazard and a decrease in biodiversity. Extremely high browsing pressure had no such effects.
