Burned Site

In 1989 a wildfire destroyed 300 ha of natural pine forest and Mediterranean woodland on Mt. Carmel, Israel. Consequently an interdisciplinary scientific effort in fire ecology was initiated in order to propose recommendations to the management authorities, Field data gathered on soil erosion in the Mt. Carmel site implied that erosion is severe only during the first winter after fire, but it does not seem to present a significant threat to longterm ecosystem recovery. The recovery of the natural vegetation mitigates erosion, and there is no special need for any precautions to be taken immediatly following fire. Salvage cutting of burned trees had no effect on pine seedling recruitment, on vegetation development and on plant species diversity. Salvage cutting did affect passerine bird community by slowing down succession rate. For successful regeneration of the pine forest the burned site need not to be planted, since the number of natural pine seedlings is sufficiently great, and there is a need to conserve the genetic and spatial variability of the forest. Although thinning has a positive effect on short-term pine survival and growth, such action is not recommended since pine seedlings are susceptible to pine bast scale (Matsococcus josephi) up to seven years, and to severe damage by porcupines. Selection caused by this bast scale might improve the resistance of the new pine forest stand. Pine seedling growing in the:microsites of the old burned pine trees should be treated carefully, since some of them, due to their fast development, appear to be the next generation of the forest. Thinning of these groups can be considered after seven years, accompanied by removal of Cistus dwarf shrubs. However, where porcupine damage is observed, thinning should be done at low rates and with no pruning of side twigs. Since animal succession is a consequence of the change and progress in vegetation structure, there is no need for animal resettlement. The concept of 'fuel breaks', combining a single massive thinning of the woody vegetation and an annual short but heavy grazing, is a management option for decreasing fire danger and future fire damage.

This study documents latent infection of Austrian and Scots pine tissues by Sphaeropsis sapinea, the causal agent of Sphaeropsis tip blight disease. Symptomless shoots from diseased or apparently healthy Austrian and Scots pine trees were cultured and analyzed for the presence of S. sapinea. Nearly half of the sampled Austrian and Scots pine trees that appeared to be completely healthy had detectable latent S. sapinea infections. More than half of the symptomless shoots on visibly diseased Austrian and Scots pine trees were also latently infected with S. sapinea. S. sapinea was isolated from symptomless shoot stems, needles, buds, immature cones, and male flowers. In symptomless infected shoots, the fungus was primarily associated with the bark and phloem tissues. Six isolates of S. sapinea from symptomless Austrian and Scots pine shoot tissues were pathogenic on Austrian pine seedlings in the greenhouse. The presence of S. sapinea in symptomless tissues of tip blight-diseased trees has important implications for disease management.

The Individual

The occurrence of growth regulators and nucleic acids in buds of red pine trees has been investigated in relation to seasonal change, position of the bud in the crown, and age of the tree. The regulators were extracted, separated by chromatography, and assayed by an Avena straight-growth test. Three growth promoters and an inhibitor were found in the buds on all occasions. All of them affected the growth of hypocotyls of red pine seedlings as well as Avena inter-nodes, and none gave an indole reaction. The regulators varied in concentration in relation to season, age, and bud position. The individual growth promoters varied independently, one of them, designated as P1, being more variable than the others. Changes in the inhibitor were frequently, but not invariably, reciprocal to those of P1. There is evidence that individual growth promoters may be concerned with separate aspects of growth. The balance between P1 and the inhibitor was related to extension growth, with the notable exception that a balance favorable to growth reappeared in September, when no growth occurs. RNA concentration declines during the summer and a deficiency of this nucleic acid could be implicated in the cessation of growth.Treatment with ammonium nitrate fertilizer caused a shift from male to female cone production and a localized increase in the number of shoots that developed in the following year. These effects were accompanied by changes in concentration of growth promoters in the buds.

In September 1989 a fire burned a large natural Pinus halepensis Mill. forest on Mt. Carmel, Israel. This paper summarizes the main results of five years of research, in which the effects of natural factors and management on the development of the forest and the vegetation were studied. It was found that the burned pine tree skeletons were correlated with the spatial pattern of seed germination.. Fewer pine seedlings were found one year after the fire near the burned trunks, but the survival and growth rate of these young pine trees was higher in the following four years. Pine ash was found to inhibit post-fire seed germination, offering a possible explanation for the apparent effect of the old burned trees on the spatial pattern of the new pine seedlings. Both laboratory experiments and field measurements indicate that the high pH of the ash, is the main factor responsible for the inhibition of germination. We examined several management regimes designed to enhance the growth of the young post-fire pine trees and assess their influence on the recovery of the forest. The results revealed that four years after fire, and three years after treatments, forest regeneration was mainly affected by the natural process while management had only a marginal effect. Management such as cutting and leaving, or cutting and removing the burned trunks and twigs from the plots, had almost no effect on species composition and cover. However, thinning of Pinus and Cistus seedlings increased survival and growth of remaining seedlings.

In 2007, a fire burned over 100000ha along the Anaktuvuk River in Alaska, causing widespread ecological disturbance. Despite efforts to understand ecosystem recovery, little is known about higher trophic levels. Here, we present qualitative findings from a preliminary bird survey of the burn scar region, conducted in 2014, at three sites representing varying severity of burn damage. We found that abundance and species richness both appear higher at a site that experienced a moderate degree of burn damage than unburned control and severely burned sites. These findings suggest that the impacts of fires on bird communities may be minimal within 7 years post fire. Furthermore, our findings highlight the need for more rigorous efforts to understand the dynamics of tundra bird community fire recovery in a rapidly changing world.

Pinus Merkusii

Desa Uwemanje terletak pada ketinggian >400 m dpl dan merupakan salah satu desa berpotensi di lereng pegunungan Gawalise. Karena berada di pegunungan maka desa ini memiliki topografi berbukit terjal dimana sebagian besar lahan memiliki tingkat kemiringan lereng lebih dari 40%, sehingga praktek pertanian termasuk agroforestri di desa ini sangat rawan terhadap erosi dan degradasi lahan lainnya. Komoditas utama terpenting di desa ini adalah Hasil Hutan Bukan Kayu seperti tegakan tusam yang telah berumur lebih dari 35 tahun dan merupakan hasil reboisasi oleh Dinas Kehutanan Kabupaten Donggala pada lahan kritis yang berada di desa ini. Tegakan tusam berperan penting dalam konservasi tanah dan penyimpan air (water reservoir) bagi sumber mata air. Namun, kondisinya saat ini sangat mengkhawatirkan, selain berumur tua, tegakan tusam banyak mati karena diserang oleh hama dan patogen. Salah satu kegiatan dalam program Ipteks Bagi Desa Mitra (IbDM) ini adalah pembibitan tusam (Pinus merkusii Jungh & de Vriese) bekerjasama dengan mitra tiga kelompok tani hutan di desa tersebut. Bibit tusam dari pembibitan ini diharapkan menjadi pengganti tegakan tusam yang telah tua atau akan ditanam pada lahan-lahan kritis yang masih luas di desa ini. Oleh karena itu, dalam rangka peningkatan pendapatan masyarakat serta usaha konservasi hutan dan perlindungan tanah dan air di desa ini, perlu dilakukan program pengabdian dalam hal teknik pembibitan tusam bagi anggota kelompok tani hutan tersebut. Metode-metode pendekatan yang ditawarkan dalam kegiatan ini adalah dalam bentuk pendidikan dan pelatihan bagi anggota kelompok tani mitra dengan menggunakan metode penyuluhan dan pendampingan yang berupa bimbingan teknis dan pembinaan kelompok tani dalam pembibitan tusam. Hasil pelaksanaan program yang telah dilaksanakan yaitu tersedianya ±3000 bibit tusam yang berkualitas yang siap ditanam oleh para anggota kelompok tani dan areal pembibitan tusam bagi kelompok tani. Selain itu, terjadi peningkatan pengetahuan dan keterampilan anggota kelompok tani hutan terutama dalam hal teknik pembibitan tusam.[The village of Uwemanje lies at an altitude of >400 m asl and is one of the potential villages on the slopes of the Gawalise mountains. Because it is located in the mountains, the village has a steep hilly topography where most of the land has a slope of more than 40%, so agricultural practices including agroforestry in this village are very vulnerable to erosion and other land degradation. The most important commodities in this village are Non-Timber Forest Products such as pine (Pinus merkusii Jungh & de Vriese) stands that have been more than 35 years old, and are the result of reforestation by the Forestry Service of Donggala District on the critical land located in this village. Pine stand plays an important role in soil conservation and water reservoir (water reservoir). However, the pine trees current condition is very worrying, in addition to old age, many pine trees die because of being attacked by pests and pathogens. One of the activities in science and technology program for Desa Mitra (IbDM) is a tusam nursery in collaboration with partners of three forest farmer groups in the village. The pine seedlings are expected to be a substitute for old pine stands or to be planted on the vast critical lands in the village. Therefore, in order to increase community income and forest conservation and soil and water protection in this village, it is necessary to do devotion program in the technique of pine nursery for members of forest farmer group. The methods of approach offered in this activity are in the form of education and training for members of partner farmer groups by using counseling and mentoring methods in the form of technical guidance and guidance of farmer groups in pine nurseries. The results of the implementation of the program that has been implemented is the availability of ± 3000 pine seedlings that are ready to be planted by members of farmer groups and pine nursery areas for farmer groups. In addition, there is an increased knowledge and skills of members of forest farmer groups, especially in terms of pine nursery techniques.]

The paper presents materials on the study and content of the accumulation of iron and manganese in the woody and herbaceous leaves of the Beskaragai belt pine forest of the dry steppe zone of Kazakhstan, as well as the ratio of iron and manganese to determine the conditions for normal plant life. The results of the research showed that the values of the biotic index in woody and herbaceous plants of the Beskaragay lentchen boron for iron are below 0.3. In the needles of pine trees, none of the zones retained the ratio between iron and manganese for the normal life of pine plants. The accumulation of manganese in herbs occurs mainly from the atmosphere. Of the two biogenic metals, only Mn in the Beskaragai pine forest plays the role of biogeochemical circulation of substances for pine needles. The values of Кн for iron are less than one in pine needles taken from different zones of the Beskaragai forest, which indicates the input of manganese into forest ecosystems, both from the soil and from the atmosphere. The ratio of the concentration of iron and manganese 2: 1, which is necessary for grasses for normal life, is observed only in the zone of unpaved roads of the Beskaragai forest. The work is of great importance for further monitoring of the state of forest ecosystems in the conditions of technogenic and aeronautical pollution of the study area.
