Estimation and evaluation of multi-decadal fire severity patterns using Landsat sensors

Retrospective identification of fire severity can improve our understanding of fire behaviour and ecological responses. However, burnt area records for many ecosystems are non-existent or incomplete, and those that are documented rarely include fire severity data. Retrospective analysis using satellite remote sensing data captured over extended periods can provide better estimates of fire history. This study aimed to assess the relationship between the Landsat differenced normalised burn ratio (dNBR) and field measured geometrically structured composite burn index (GeoCBI) for retrospective analysis of fire severity over a 23 year period in sclerophyll woodland and heath ecosystems. Further, we assessed for reduced dNBR fire severity classification accuracies associated with vegetation regrowth at increasing time between ignition and image capture. This was achieved by assessing four Landsat images captured at increasing time since ignition of the most recent burnt area. We found significant linear GeoCBI–dNBR relationships (R2 = 0.81 and 0.71) for data collected across ecosystems and for Eucalyptus racemosa ecosystems, respectively. Non-significant and weak linear relationships were observed for heath and Melaleuca quinquenervia ecosystems, suggesting that GeoCBI–dNBR was not appropriate for fire severity classification in specific ecosystems. Therefore, retrospective fire severity was classified across ecosystems. Landsat images captured within ~ 30 days after fire events were minimally affected by post burn vegetation regrowth.

Fauna community trends during early restoration of alluvial open forest/woodland ecosystems on former agricultural land

Vertebrate fauna was studied over 10 years following revegetation of a Eucalyptus tereticornis ecosystem on former agricultural land. We compared four vegetation types: remnant forest, plantings of a mix of native tree species on cleared land, natural regeneration of partially cleared land after livestock removal, and cleared pasture land with scattered paddock trees managed for livestock production. Pasture differed significantly from remnant in both bird and nonbird fauna. Although 10 years of ecosystem restoration is relatively short term in the restoration process, in this time bird assemblages in plantings and natural regeneration had diverged significantly from pasture, but still differed significantly from remnant. After 10 years, 70 and 66% of the total vertebrate species found in remnant had been recorded in plantings and natural regeneration, respectively. Although the fauna assemblages within plantings and natural regeneration were tracking toward those of remnant, significant differences in fauna between plantings and natural regeneration indicated community development along different restoration pathways. Because natural regeneration contained more mature trees (dbh > 30 cm), native shrub species, and coarse woody debris than plantings from the beginning of the study, these features possibly encouraged different fauna to the revegetation areas from the outset. The ability of plantings and natural regeneration to transition to the remnant state will be governed by a number of factors that were significant in the analyses, including shrub cover, herbaceous biomass, tree hollows, time since fire, and landscape condition. Both active and passive restoration produced significant change from the cleared state in the short term.

Native Phloem and Wood Borers in Australian Mediterranean Forest Trees

Native Mediterranean forests in Australia are dominated by two tree genera, Eucalyptus and Acacia, while Pinus and Eucalyptus dominate plantation forestry. In native forests, there is a high diversity of phloem and wood borers across several families in the Coleoptera and Lepidoptera. In the Coleoptera, cerambycid beetles (Cerambycidae), jewel beetles (Buprestidae), bark, ambrosia and pinhole beetles (Curculionidae) and pinworms (Lymexelidae) are some of the most commonly found beetles attacking eucalypts and acacias. In the Lepidoptera, wood moths (Cossidae), ghost moths (Hepialidae) and borers in the Xyloryctidae (subfamily Xyloryctinae) are most common. In contrast to native forests, there is a much more limited range of native insects present in Australian plantations, particularly in exotic Pinus spp. plantations, although eucalypt plantations do share some borers in common with native forests. This chapter reviews the importance of these borers in Australian forests primarily from an economic perspective (i.e. those species that cause damage to commercial tree species) and highlights a paucity of native forest species that commonly kill trees relative to the large scales regularly seen in North America and Europe.

Characterisation of wood–water relationships and transverse anatomy and their relationship to drying degrade

Characterisation of a number of key wood properties utilising ‘state of the art’ tools was achieved for four commercial Australian hardwood species: Corymbia citriodora, Eucalyptus pilularis, Eucalyptus marginata and Eucalyptus obliqua. The wood properties were measured for input into microscopic (cellular level) and macroscopic (board level) vacuum drying models currently under development. Morphological characterisation was completed using a combination of ESEM, optical microscopy and a custom vector-based image analysis software. A clear difference in wood porosity, size, wall thickness and orientation was evident between species. Wood porosity was measured using a combination of fibre and vessel porosity. A highly sensitive microbalance and scanning laser micrometres were used to measure loss of moisture content in conjunction with directional shrinkage on micro-samples of E. obliqua to investigate the validity of measuring collapse-free shrinkage in very thin sections. Collapse-free shrinkage was characterised, and collapse propensity was verified when testing thicker samples. Desorption isotherms were calculated for each species using wood–water relations data generated from shrinkage experiments. Fibre geometry and wood shrinkage anisotropy were used to explain the observed difficulty in drying of the different species in terms of collapse and drying stress-related degrade.

Prey of the silver-headed antechinus (Antechinus argentus), a new species of Australian dasyurid marsupial

The silver-headed antechinus (Antechinus argentus) is one of Australia’s most recently described mammals, and the single known population at Kroombit Tops in south-east Queensland is threatened. Nothing is known of the species’ ecology, so during 2014 we collected faecal pellets each month (March–September) from a population at the type locality to gather baseline data on diet composition. A total of 38 faecal pellets were collected from 12 individuals (eight females, four males) and microscopic analysis of pellets identified seven invertebrate orders, with 70% combined mean composition of beetles (Coleoptera: 38%) and cockroaches (Blattodea: 32%). Other orders that featured as prey were ants, crickets/grasshoppers, butterflies/moths, spiders, and true bugs. Given that faecal pellets could only be collected from a single habitat type (Eucalyptus montivaga high-altitude open forest) and location, this is best described as a generalist insectivorous diet that is characteristic of other previously studied congeners.

Regeneration ecology and woody species diversity in the remnant natural forest at Wondo Genet, Ethiopia – Potential for landscape restoration

Regeneration ecology, diversity of native woody species and its potential for landscape restoration was studied in the remnant natural forest at the College of Forestry and Natural Resources at Wondo Genet, Ethiopia. The type of forest is Afromontane rainforest , with many valuable tree species like Aningeria adolfi-friederici, and it is an important provider of ecological, social and economical services for the population that lives in this area. The study contains two parts, natural regeneration studies (at the natural forest) and interviews with farmers in the nearby village of the remnant patch. The objective of the first part was to investigate the floristic composition, densitiy and regeneration profiles of native woody species in the forest, paying special attention to woody species that are considered the most relevant (socio-economic). The second part provided information on woody species preferred by the farmers and on multiple uses of the adjacent natural forest, it also provided information and analysed perceptions on forest degradation. Systematic plot sampling was used in the forest inventory. Twenty square plots of 20 x 20 m were assessed, with 38 identified woody species (the total number of species was 45), representing 26 families. Of these species 61% were trees, 13% shrubs, 11% lianas and 16% species that could have both life forms. An analysis of natural regeneration of five important tree species in the natural forest showed that Aningeria adolfi-friederici had the best regeneration results. An analysis of population structure (as determined by height classes) of two commercially important woody species in the forest, Aningeria adolfi-friederici and Podocarpus falcatus, showed a marked difference: Aningeria had a typical “reversed J” frequency distribution, while Podocarpus showed very low values in all height classes. Multi dimensional scaling (MDS) was used to map the sample plots according to their similarity in species composition, using the Sørensen quantitative index, coupled with indicator species analysis .Three groups were identified with respective indicator species: Group 1 – Adhatoda schimperiana, Group 2 – Olea hochstetteri , Group 3 – Acacia senegal and Aningeria adolfi-friederici. Thirty questionnaire interviews were conducted with farmers in the village of Gotu Onoma that use the nearby remant forest patch. Their tree preferences were exotic species such as Eucalyptus globulus for construction and fuelwood and Grevillea robusta for shade and fertility. Considering forest land degradation farmers were aware of the problem and suggested that the governmental institutions address the problem by planting more Eucalyptus globulus. The natural forest seemed to have moderate levels of disturbance and it was still floristically diverse. However, the low rate of natural regeneration of Podocarpus falcatus suggested that this species is threatened and must be a priority in conservation actions. Plantations and agroforestry seem to be possible solutions for rehabilitation of the surrounding degraded lands, thereby decreasing the existent pressure in the remnant natural forest.

Evaluation of the profitability of fast-growing tropical trees.

The profitability of fast-growing trees was investigated in the northeastern and eastern provinces of Thailand. The financial, economic, and tentative environmental-economic profitability was determined separately for three fast-growing plantation tree species and for three categories of plantation managers: the private industry, the state (the Royal Forest Department) and the farmers. Fast-growing tree crops were also compared with teak (Tectona grandis), a traditional medium or long rotation species, and Para rubber (Hevea brasiliensis) which presently is the most common cultivated tree in Thailand. The optimal rotation for Eucalyptus camaldulensis pulpwood production was eight years. This was the most profitable species in pulpwood production. In sawlog production Acacia mangium and Melia azedarach showed a better financial profitability. Para rubber was more profitable and teak less profitable than the three fast-growing species. The economic profitability was higher than the financial one, and the tentative environmental-economic profitability was slightly higher than the economic profitability. The profitability of tree growing is sensitive to plantation yields and labour cost changes and especially to wood prices. Management options which aim at pulpwood production are more sensitive to input or output changes than those options which include sawlog production. There is an urgent need to improve the growth and yield data and to study the environmental impacts of tree plantations for all species and plantation types.

Estimation of Aboveground Phytomass of Plantations Using Digital Photogrammetry and High Resolution Remote Sensing Data

The study follows an approach to estimate phytomass using recent techniques of remote sensing and digital photogrammetry. It involved tree inventory of forest plantations in Bhakra forest range of Nainital district. Panchromatic stereo dataset of Cartosat-1 was evaluated for mean stand height retrieval. Texture analysis and tree-tops detection analyses were done on Quick-Bird PAN data. The composite texture image of mean, variance and contrast with a 5x5 pixel window was found best to separate tree crowns for assessment of crown areas. Tree tops count obtained by local maxima filtering was found to be 83.4 % efficient with an RMSE+/-13 for 35 sample plots. The predicted phytomass ranged from 27.01 to 35.08 t/ha in the case of Eucalyptus sp. while in the case of Tectona grandis from 26.52 to 156 t/ha. The correlation between observed and predicted phytomass in Eucalyptus sp. was 0.468 with an RMSE of 5.12. However, the phytomass predicted in Tectona grandis was fairly strong with R-2=0.65 and RMSE of 9.89 as there was no undergrowth and the crowns were clearly visible. Results of the study show the potential of Cartosat-1 derived DSM and Quick-Bird texture image for the estimation of stand height, stem diameter, tree count and phytomass of important timber species.

Estado actual del bosque de galería en un tramo de la parte media de los ríos Ochomogo y Nandarola, municipio de Nandaime, Granada, Nicaragua, 2014

La Facultad de Recursos Naturales y del Ambiente (FARENA) en conjunto con el proyecto UNA-FAGRO DEPARTIR/ORGANIZACIÓN MUNDIAL PARA LA SALUD Y SEGURIDAD ALIMENTARIA, FAO, consideraron como objetivo principal Diagnosticar el estado actual del bosque de galería en los ríos Ochomogo y Nandarola, del municipio de Nandaime, Granada. En el río Nandarola se inventarió un área de 23.33 ha, encontrándose 321 árboles en 62 especies y 29 familias; la especie más representativa es el Guácimo de ternero(Guazuma ulmifolia Lam) con 30 individuos, y la familia más representativa es Mimosaceae con ocho especies. El área inventariada del río Ochomogo fue de 8.18 ha, se identificaron 154 árboles en 37 especies y 24 familias; la especie más abundante es Tigüilote(Cordia dentata Poir) con 19 individuos, la familiacon mayor representatividad es la Mimosaceae con cinco especies. Las variables silviculturales, iluminación respecto al río Nandarola equivale a un 51% de iluminación vertical plena, un 52% poseen fustes rectos sin ningún daño, y un 65% se encuentra libre de lianas. Por otro lado en el río Ochomogo se encontró un 57% de árboles que recibe iluminación vertical plena, con una calidad de fuste recto sin ningún daño de 45% y el 65% están libres de lianas. En general se puede decir que la población local y circundante ejerce presión sobre el recurso bosque; el caudal del río ha disminuido notoriamente por las actividades de extracción de madera para consumo energético; se evidencia la sustitución de especies nativas por exóticas como Teca (Tectona grandis L.F), Eucalipto (Eucalyptus spp.) y Neem(Azadirachta indica A. Juss) en las áreas de las riveras de los ríos, el aumento de áreas para potreros y el establecimiento de pasto, de plantaciones de cultivos de plátanos y de micro fábricas de ladrillos.

Optimización de la metodología para la producción de hongos comestibles

El cultivo de hongos comestibles saprófitos constituye un sistema de producción-consumo, que ha adquirido gran relevancia social, económica y ecológica. Con el fin de abaratar costes a la vez que aprovechar y reciclar residuos forestales, el objetivo de este trabajo se ha centrado en evaluar la viabilidad del aserrín de Eucalyptus globulus como soporte del cultivo en bolsa de Lentinula edodes (hongo comercializado conocido como Shiitake) y Agrocybe aegerita (hongo no comercializado comúnmente llamado Seta de Chopo). Se han evaluado 6 formulaciones, todas ellas con el aserrín como componente principal y con adición de diferentes suplementos: cereales (salvado y mijo), un controlador del pH (CaCO3) y un estimulador de crecimiento (CaSO4). Se ha determinado el crecimiento miceliar sobre cada uno de los sustratos, así como la producción de carpoforos (tanto en cantidad como en calidad) y la duración del periodo de fructificación. La mezcla más efectiva para la producción de L. edodes fue aquella que contenía yeso y azúcar mientras que para A. aegerita el salvado resultó ser el mejor suplemento.

萱草属的进化与分类

根据现有记载，萱草属约有20种，主要分布在东亚，由于种间在外部形态和核型上的高度相似性，加之长期人工栽培，使本属植物的分类成为一个难题，我们做了大量的野外调查和温室栽培试验，获得了一些有意义的观察结果，对核型变异做了详细定量分析：系统观察了花粉扫描电镜特征，为了揭示属内可能的表征和分支关系，运用聚类分析，主成分分析及简约分析对属下类群做了定量研究．本文得到如下主要结论． 1．虽然迄今为止许多核型观察结果未能得到有分类学意义的结论，运用数量分析方法比较各分类群核型定量变异结果表明，其分类学意义是明显的，例如，北黄花菜、黄花菜和小黄花菜三者外部形态很一致，核型亦高度相似：大苞萱草和多花萱草的核型公式虽与前三者相同，但已出现明显的数量变异．同样，北萱草，折叶萱草和西南萱草虽有相同核型公式，亦出现明显数量变异．萱草则与所有其他类群的核型均有明显差别．核型对称性分析表明，臂比不对称性出现一个由低到高的演变序列：但长度不对称性与此无明显相关性．萱草和折叶萱草的臂比不对称性最低，西南萱草和北萱草升高，黄花菜，大苞萱草和多花萱草等最高． 2．观察到三种类型花粉;舟形具网纹，舟形具疣纹和亚球形具疣纹．萱草，北萱草，大苞萱草，北黄花菜，黄花菜，小黄花菜及多花萱草具第一种类型花粉;折叶萱草和西南萱草具第2种类型花粉;矮萱草具第三种花粉．以广义百合科其他类群作为复合外类群进行比较，推测花粉形态的演化序列为：舟形具网纹一舟形具疣纹一亚球形具疣纹． 3．在外部形态上，萱草因具二叉分枝花序，叶型苞片，根膨大适中，花蕾顶部绿色及花筒占花被比例较小等原始性状状态，结合不对称性较低的核型特征和舟形具网纹花粉特征，是现存种类中最原始类群;折叶萱草及北萱草等具较短的花筒，二叉分枝花序，单色花被及花蕾部绿色等特征显得进化程度不高．黄花菜因具夜间开花习性，长花筒，叶鞘红色等状态被认为是进化类群，大苞萱草高度压缩的花序形成头状花序，具总苞状宽大苞片及绳索状根被认为是特化类群，矮萱草个体矮小，单花，具亚球形疣纹花粉亦被认为是高度特化类群．外部形态，花粉特征，核型及地理分布之间存在着相关性;随地理水平分布由南向北，外部形态特征由原始到进化，核型不对称性由低到高：随地理垂直分布由低向高，形态特征由复杂到简化，核型不对称性由低到高，花粉形态由舟形具网纹到舟形具疣纹再到亚球形具疣纹，这两种趋势结合起来构画出了本属植物演化和地理分布的基本轮廊． 4．萱草是一个孤立的属，没有明确的外类群可供比较．在现存类群中．Dahlgren等(1985)认为本属与分布在非洲，地中海地区，西亚及中亚的Asphodeloideae（亚科）有较多的共有特征．本文比较了两个类群之后发现，萱草不但在许多一般特征上与Asphodeloideae -致，而且在小孢子同时型发生及含蒽醌等被认为是Asphodeloideae典型属性的特征上亦与后者相同．这些共有特征显示出二 者在系统发育上一定的联系．进一步比较发现两者在有差异的特征中，萱草属显得较为进化．二者的分布区是完全不同的;Asphodeloideae分布在中亚及其以西地区和非洲，而本属分布在东亚，延及西伯利亚，据本文分析，欧洲生长的一个种(H.lilioasphodelus，北黄花菜)是归化类群．北美和台湾没有自然分布，但栽培植物均生长良好，而且已有归化植物．由此似乎可以推测，本届的祖先与Asphodeloideae的祖先有亲缘关系，这种关系似可远溯到第三纪古地中海时期，或许当时与Asphodeloideae祖先有关系的一个分支分布于古地中海东南缘的康滇古陆，即与现今横断山地区相应的地区，由于喜玛拉雅造山运动引起的地质，地理和气候剧变，某些类群灭绝了，一个类群发展成现今的萱草属． 5．由于本属各分类群间形态及核型相似性程度较高，种间极易（人工）杂交，似无必要在属与种间增设组或系，根据本文研究结果及参考有关分类文献（国外种类），我们将萱草属处理为10种2亚种13变种：H.darrowiana Hu;小萱草(H.dumortieri Morr.)及北萱草(var. esculenta (Koidz.) Kitamura;西南萱草(H.forrestii Diels);萱草(H.fulva (L.) L.)及var. aurantiaca (Baker) Hotta, var. disticha (Donn.) Baker，重瓣萱草(var. kwanso Regel)，var. littorea (Makino)Hotta，长菅萱草(var. longituba (Miq.) Maxim，var. maculata Baroni，var. pauciflora Hotta et Matsuoka, var. rosea Stout, var. sempervirens (Araki) Hotta; H. hakuunensis Nakai;北黄花菜 (H. lilioasphodelus L. Var. lilioasphodelus)及黄花菜(ssp. citrina (Baroni) Xiong)，小黄花菜(ssp. minor(Mill.) Xiong)，var. corcana (Nakai) Xiong;大苞萱草 (H. middendorfii Trautv. et Mey var. middendorfii)及var. exaltata (Stout) Kitamura，长苞萱草(var. longibracteata Xiong);多花萱草(H. multiflora Stout);矮萱草(H. nana Smith ct Forrest);折叶萱草(H.plicata Stapf)。
