Ecological Impact of Forest Fires and Subsequent Restoration in Chile

This note analyzes the effects forest fires in Chile have on vegetation and subsequent ecological restoration. We analyze why forest fires have been a main factor that affects the environment and causes the ecosystem to deteriorate, leading to loss of native forests, species extinction, damage to the urban population, and others. The data examined are derived from fire hotspots in Chile's central and central-south zones (33 • 00 S-41 • 57 S) between 1985 and 2017. We also analyze some key aspects for restoration priorities such as studying affected areas and posterior consequences. Finally, we evaluate actions the country has already taken, and propose further appropriate preventive and restoration measures.

“…Based on the available data, the recurrence of large wildfires is threatening the conservation of P. nigra ecosystems, as very little natural regeneration occurs in these species' forests after wildfires. Because the black pine is a non-serotinous pine, and because it has no adaptive mechanisms to crown fires, the natural regeneration of the species is limited to a short distance from the unburnt stands [3,10,12]. Seed dispersal models have shown that the natural regeneration of the black pine occurs at distances no greater than 100 m, depending on the following factors: the side seeding potential, site characteristics (soil fertility, moisture, slope, etc.…”

Fertilization and Shading Trials to Promote Pinus nigra Seedlings’ Nursery Growth under the Climate Change Demands

et al. 2021

Pinus nigra is one of the most widely used tree species for reforestation within its geographical distribution, as well as being a potential substitute for other tree species in Central Europe under future climate scenarios. P. nigra is transplanted into the field as two-year or three-year old seedlings because of its relatively low growth rate in the nursery. This study investigated the effects of fertilization programs and shading on P. nigra seedlings, aiming to accelerate early growth, and thus to reduce the nursery rearing time. The experiment (a completely randomized block design) was conducted in an open-air nursery by sowing seeds from Grevena, Northern Greece, in Quick pots filled with peat and perlite in a 2:1 ratio. The seedlings were subjected to two levels of fertilization—5 and 10 g L−1 NPK (30-10-10)—and two shading levels: 50% and 70%. At the ends of the first and second nursery growing season, we recorded the seedlings’ above- and below-ground morphology and biomass data. The results show that the application of all of the treatments produced seedlings which met the targeted quality standards for outplanting. However, the combination of a high fertilization rate and low shading level resulted in seedlings of a higher morphological quality, which is often considered to be an indicator for a successful seedling establishment in the field.
