THE MOST IMPORTANT NWFPS FROM DAMBOVITA COUNTY IDENTIFIED THROUGH THE ANALYTICAL HIERARCHY PROCESS

The present paper analyses the main non-wood forest products (NWFPs) characteristic to Dâmboviţa County, by using a specialised decision-making analysis software based on the analytical hierarchy process (AHP). The work starts with a short description of Dâmboviţa County and of the NWFP concept. This is followed by the method in which the analysed products were grouped, as well as their analysis and classification method based on 19 criteria. Furthermore, the analytical hierarchy process (AHP) is also well explained and defined. A total number of eight NWFP were analysed, belonging to the following categories: mushrooms, products originating from trees, plants and animals. The results section presents the most important non-wood products from Dâmboviţa County as well as the advantages and disadvantages of the analysed criteria. Based on the obtained results, the most important NWFPs from Dâmboviţa County are Cantharellues cibarius and Sorbus torminalis, while the least important one is Alium ursinum

CIRSIUM GENUS IN "ALEXANDRU BELDIE" HERBARIUM FROM "MARIN DRĂCEA” NATIONAL INSTITUTE FOR RESEARCH AND DEVELOPMENT FOR FORESTRY

Cirsium Genus is well represented in “Alexandru Beldie” Herbarium by 60 species and numerous subspecies. The herbarium, hosted by „Marin Drăcea” National Institute for Research and Development in Forestry, also contains additional information for each sample, such as: the plants’ harvesting places, harvesting dates and the name of specialists who have collected the sample. The present paper synthesizes, organizes and presents all the samples of Cirsium genus from this herbarium, taking into account different characteristics stored on plates. The obtained results were then rendered in graphic representations of harvesting periods, in a harvesting map and in a list of specialists who have collected the plants. The introduction contains a short description of the herbarium with the most representative genres, followed by a description of the method used for obtaining the systematization of the Cirsium genre. This was obtained by recording, for each sample, the number and drawer, the collection name, the specialist who collected the plant as well as the harvesting date and place. A conservation degree was also given from 1 to 4, where 1 means a very good conservation degree, and 4 is a very weak conservation degree. The most proliferous period for the herbarium’s development with Cirsium genus species was recorded between 1881-1900. A Cirsium pauciflorum Spr. plant is the oldest plant of this genus present in the herbarium and dates back to 1835, being collected from Călimani Mountains. Cirsium samples have been collected from all Europe with a focus on our country. The conclusions of the paper present interesting aspects regarding Cirsium genus samples from “Alexandru Beldie” Herbarium

AGROSTIS SPECIES PRESENT IN THE “ALEXANDRU BELDIE” HERBARIUM FROM “MARIN DRĂCEA” NATIONAL INSTITUTE FOR RESEARCH AND DEVELOPMENT IN FORESTRY

Well represented within Al. Beldie Herbarium from „Marin Drăcea” National Institute for Research and Development in Forestry, the Agrostis Genus stands out through the important number of plates that contain plants representative for this Genus, as well as through the information contained within it. This information relates to the plants’ gathering places, covering almost our entire country, and to the renowned specialists that have contributed to the collection’s development, gathering or identifying plants belonging to the Agrostis Genus.The present paper summarises and presents the Agrostis species present in the Herbarium based on their gathering place and year, as well as after the specialists that has collected them. Furthermore, the most important Agrostis species are described based on the abundance from the Herbarium’s maps, their rarity or endangerment in the natural environment.The paper starts with a description of the Herbarium, continuing with presenting the studied material (93 plates that contain 21 Agrostis species). The materials and methods used for elaborating the present paper are then presented together with a systematization of plants and the description of the most important ones.From the Agrostis Genus, the Herbarium accommodates a sample of a species that appears in the Red Book of vascular plants from Romania (Agrostis alpina Scop.). Furthermore, the Herbarium can also take pride of old plants with an historical value, collected almost 150 years ago (Agrostis maritima DC, 1874, Coulon, France).In addition, the present paper presents a graphic of gathering periods for the plants belonging to this Genus, followed by a map of their gathering places from Romania.The conclusions present some important aspects regarding the Agrostis species and samples present in the above-mentioned Herbarium.

APPLICATION OF THE ANALYTIC HIERARCHY PROCESS IN SELECTION OF THE MOST IMPORTANT NON-WOOD FOREST PRODUCTS FOR DOLJ COUNTY

In Romania, non-wood forest products (NWFPs) are mainly represented by wildlife species of hunting interests, fish from the waters included into the forest fund, forest berries, forest seeds, edible mushrooms, medicinal and aromatic plants and resin. The NWFPs belong to their owners with the exception of the first two categories.The aim of this study was to highlight the most important NWFPs from Dolj County. Theanalyzemodel was based on Analytic Hierarchy Process and 19 criteria and 8 alternatives (NWFPs) were used.The processing of the data was done using Expert Choice Desktop software.The eight selected NWFPs consisted inparasol mushroom, milk-caps, oak seeds, black berries, berries of common hawthorn, Saint John’swort, European hare and common quail.According to the AHP results, the most important non-wood forest product for Dolj County is the European hare, while the less important one is Saint John' worth.The results of this study represent an important contribution to the evaluation of the potential of the NWFPs for Dolj County with a special view on their harvesting, marketing and other linked activities

Damage and Tolerability Thresholds for Remaining Trees after Timber Harvesting: A Case Study from Southwest Romania

The present study analyses the damage of remaining trees after timber harvesting from 24 logging sites from southwest Romania. The purpose was to establish tolerability thresholds within which damaged trees recover in a short amount of time, reducing the possibility of further rot apparition and tree health deterioration. Observations were resumed after the growing season had passed. Healed damage was analysed in regard to damage type, width, orientation and tree circumference. By using the ratio between the width of healed damage and the circumference of trees as experimental variants, equations were elaborated to determine the tolerance threshold of trees in logging. This is expressed as a maximum value between the damage width and the damaged tree circumference for which the damage is curable. The correlation between the circumference and the abovementioned relation was analysed, and differences between the values of the analysed relation for different cardinal orientations of the damage were statistically tested. The value of this ratio, which can be considered a tolerance threshold for trees in logging, records values of 0.09 (for thinnings, for cuttings to increase the light availability for regeneration and for final cuttings from shelterwood systems) and 0.10 (for first-intervention cuttings, as well as preparatory and seed cutting from shelterwood systems or selections systems)

Improving the Content of Chemical Elements from the Soil of Waste Heaps Influenced by Forest Vegetation—A Case Study of Moldova Nouă Waste Heaps, South-West Romania

The present article emphasizes the influence of forest vegetation on improving the content of toxic elements from soil, increasing the content of micro and macro elements as well as correlating these variations with characteristics of forest vegetation from the studied areas—Moldova Nouă waste heaps, South-West Romania. The research involved comparing and observing the differences in the content of micro, macro, and toxic elements (Fe, Pb, Zn, and Cd) between the soil of waste heaps from Moldova Nouă from areas with forest vegetation and the content of these elements analyzed 31 years ago during the projection of afforestation works, when forest vegetation was missing. The differences were correlated with stand characteristics of forest vegetation. We observed a significant increase for Fe and a significant decrease for Zn and Cd. The influence of forest vegetation of the variation on the soil’s chemical composition was studied for the chemical elements that previously showed significant differences (Fe, Zn, and Cd). The averages of the statistically significant differences for the concentration of each analyzed element (Fe, Zn, and Cd) were correlated with the characteristics of the stands from the studied sampling points. The variation in time for Fe, Zn, and Cd and actual content of P, Cu, Mg were correlated especially with the average height of trees
