Invasive Plant Species

Historically, and based on the latest conditions, Samboja Research Forest has a fairly high vulnerability to the presence of invasive species that can interfere with ecosystem stability and forest succession. However, data collection and risk assessment of invasive species have not been conducted in the forest area. The study was carried out to support the management of Samboja Research Forest, particularly in controlling invasive species. The study was conducted with exploration techniques in open areas, secondary forests, and primary forests. The density and frequency data of invasive plants were obtained using random plots in secondary and primary forest areas. The results showed the presence of 52 invasive plant species in the Samboja Research Forest area with dominance by shrubs and herbs. Based on plants distribution and density, four crucial invasive plant species in Samboja Research Forest were identified, namely: Acacia mangium, Spathodea campanulata, Miconia crenata, and Piper aduncum. The management of invasive species was carried out in two stages, short term, through manual weeding, and in the long term, with the prevention, eradication, and periodic risk assessment.Keywords: invasive alien species, Kalimantan, eradication, Spathodea campanulata

Uma espécie exótica invasora é definida como uma planta estranha que se propaga naturalmente em habitats naturais ou seminaturais, produzindo mudanças na composição, estrutura ou nos processos dos ecossistemas. No Brasil, os registros da dimensão do problema são deficientes, embora várias espécies já sejam consagradas como invasoras. No Maranhão, não havia nenhum estudo sobre espécies vegetais invasoras, embora registros e observações indiquem invasões em variados ambientes. Na ilha de São Luís, a invasão de áreas por um número de espécies tem se tornado aparente, com muitos pontos das áreas dos municípios invadidos por espécies vegetais introduzidas. Este estudo teve como objetivo principal levantar, identificar, quantificar e mapear as espécies invasoras vegetais na ilha de São Luís. Foram localizadas e identificadas cinco espécies invasoras principais que vêm ocupando e modificando ambientes na ilha de São Luís. São elas: 1) Leucena - Leucaena leucocephala (Lam.) de Wit. (Fabaceae); 2) Amendoeira - Terminalia cattapa L. (Combretaceae); 3) Fios de Ouro - Cuscuta racemosa Mart. (Convolvulaceae); 4) Saco de Velho - Calotropis procera (Aiton) W. T. Aiton (Apocynaceae); 5) Acácia Australiana - Acacia mangium Willd. (Fabaceae). Estas cinco espécies invasoras foram localizadas e amostradas em 420 pontos nos quatro municípios da ilha. As áreas invadidas foram amostradas com relação às espécies invasoras e também em relação às espécies acompanhantes principais. Imagem aérea da ilha de São Luís foi utilizada para localizar as formações vegetais e produzir um mapa de distribuição das espécies invasoras na ilha de São Luís.   A B S T R A C TAn alien invasive species is defined as a strange plant that propagates naturally in natural or semi-natural habitats, producing changes in the composition, structure or processes of ecosystems. In Brazil, records of the scale of the problem are deficient, although several species are already known as invasive. In Maranhão there were no studies on invasive plant species, although records and observations indicate invasions in various environments. On the island of São Luís, invasion by a number of species has become apparent, with many areas of the municipalities invaded by introduced plant species. The main objective of this study was to identify, quantify and map the invasive plant species on the island of São Luís. Five main invasive species were located and identified that have been occupying and modifying environments on the island of São Luís: 1) Leucena - Leucaena leucocephala (Lam.) De Wit. (Fabaceae); 2) Amendoeira - Terminalia cattapa L. (Combretaceae); 3) Fios de Ouro - Cuscuta racemosa Mart. (Convolvulaceae); 4) Saco de Velho - Calotropis procera (Aiton) W. T. Aiton (Apocynaceae); 5) Acacia Australiana - Acacia mangium Willd. (Fabaceae). These five invasive species were located and sampled at 420 sites in the four municipalities of the island. The invaded areas were sampled in relation to the invasive species and also in relation to the main accompanying species. An aerial image of the island of São Luís was used to locate plant formations and to produce a distribution map of the invasive species on the island of São Luís.Keywords: Invasive Species, Sampling, Mapping, São Luís, Maranhão

Butterfly diversity was recorded from Nov (2013) - May (2014) in Pookode region. A total number of 128 species recorded from the five families; Nymphalidae (46 species) Lycaenidae (28 species), Hesperiidae (22 species), Pieridae (17 species) and Papilionidae (15 species) respectively. During the survey invasive plant species were also recorded. There were 36 species of invasive plants from 18 families identified from the study area. More butterflies were attracted towards nectar offering invasive plants. Chromolaena odorata, Ipomea cairica, Lantana camara, Merremia vitifolia, Mikania micrantha, Mimosa diplotricha, Pennisetumpolystachyon, Pteridium aquilinum, Quisqualis indica and Sphagneticola trilobata were the major invasive plants found in the Pookode region and their flower attracts butterfly for pollination. Even though nectar offered by the plants are supportive for growth, in long run these species can affect butterfly population bydeclining native host larval plant species for butterfly reproduction. Invasive species compete with the native flora and reduce its population. Management practices like physical, chemical and modern bio control measures could be used for eradicating of invasive plants. Wise use of invasive plants for other economical purpose such as bio-fuel, medicinal purpose, bio-pesticide and handicraft could be suggested. Successful management of invasive species are needed for conserving Lepidoptera fauna and other native biota of the area.

The floristic diversity of Deliblato sands SNR is significantly endangered by the spread of invasive plants. In addition to field research, which included the collection of plant material in the area of Deliblato sands SNR, primary and secondary data was collected in this paper. The primary data for the purposes of this study was obtained by applying a questionnaire technique to the management of the protected area - PE ?Vojvodinasume? and an expert interview technique to a representative of the Provincial Institute for Nature Conservation. The secondary data was collected to gain a better and broader understanding of the management of Deliblato sands SNR. Based on the field investigations, the analysis of primary and secondary data on invasive plant species was also recognized as a key threatening factor. An analysis of the floristic structure and composition of these plant species, their origin, as well as the manner of their propagation and reproduction was carried out, in order to make a recommendation on the preventive measures for the protection and suppression of invasive plant species and to improve the habitat. In the area of Deliblato sands SNR, 39 invasive plant species (4,33% of the total flora) were found with different invasiveness categories, among which herbaceous, annual, North American species from the Compositae family prevail. Protection measures include the mapping of habitats of invasive species, establishing cooperation with managers and scientific institutions, constant monitoring of endangered habitats and plant species, as well as the creation of a special sector responsible for enhancing biodiversity.

Large Scale Disturbance

AbstractInvasive plant species degrade ecosystems in many ways. Controlling invasive plants is costly for government agencies, businesses, and individuals. North central Colorado is currently experiencing large-scale disturbance, and millions of acres are vulnerable to invasion because of natural and socioeconomic processes. Mountain pine beetles typically endemic to this region have reached epidemic proportions, with up to 80% tree mortality, which opens growing space for invasive plants. In socioeconomic terms, the popularity of this amenity-rich region for tourists and in-migrants has resulted in increased development, often bordering the public land that is common in the American West. Increased recreational access and the construction of new roads and infrastructure disturb ecosystems in an increasingly fragmented landscape. A survey was mailed to more than 4,000 households in a five-county region of north central Colorado to gauge public awareness and attitudes regarding invasive plant species, helping to illuminate whether the public shows a capacity to help land managers detect and respond to invasive plants before they profoundly alter the local ecosystem. Although 88% of respondents had heard or read about invasive plant species, far fewer were familiar with specific, locally targeted species, and fewer still had taken any action to control these species. The overall awareness and concern about invasive plants in the area indicated a capacity for more public participation in management.

Nipf Owners

We investigated nonindustrial private forest (NIPF) owners' invasive plant risk perceptions and mitigation practices using statistical analysis of mail survey data and qualitative analysis of interview data collected in Oregon's ponderosa pine zone. We found that 52% of the survey sample was aware of invasive plant species considered problematic by local natural resource professionals; 70% was concerned about these species; and 46% had treated invasive plants on their parcels. Owners' perceptions of invasive plant risks fell along a spectrum ranging from a lack of awareness or concern, to the view that invasive plant infestations have discrete causes and controllable consequences, to the perception that incursions by invasive plants have diffuse causes and uncontrollable effects. Being aware or concerned about invasive plant species were predictors (p ≤ 0.001) of whether owners treat their parcels to control invasive plants. Holding wildlife habitat and/or biodiversity as an important forest management goal was also a predictor (p ≤ 0.08) of whether owners treated their parcels to control invasive plants. Some owners were sensitive to the risks of invasive plant infestations from nearby properties, and a surprisingly high percentage of respondents had cooperated with others in forest management activities previously. Our findings suggest three approaches to increasing the frequency of invasive plant mitigation by NIPF owners that hold promise: (1) raising awareness and concern about invasive plants and their impacts on forest management goals that owners care about, such as wildlife habitat and/or biodiversity; (2) providing assistance to help owners mitigate invasive plants they feel unable to control; and (3) engaging owners in coordinated efforts across ownership boundaries to address invasive plant risks.

AbstractThe purpose of this study was to determine the effect of whole-plant composting on the viability of seeds and other propagules of the invasive plant species waterhyacinth, waterlettuce, hydrilla, and giant reed while producing a valuable compost product. Invasive species were subjected to preliminary germination and growth tests and oven mortality tests to evaluate whether species distribution was via seeds, vegetative propagules, or both, as well as whether the composting process had the potential, through the high temperatures obtained, to kill seeds and other propagules. Germination and growth tests determined the means by which invasive species spread. Oven tests determined the temperatures at which unscarified and scarified seeds and propagules were rendered inviable. Achieving temperatures of at least 57.2 C was necessary within constructed compost piles to effectively kill the plants without the danger of redistribution. In the field, the study successfully developed a large-scale composting operation using invasive plant species as the primary feedstock. Analysis of field-scale composting showed final materials were within satisfactory to ideal levels for samples analyzed by the U.S. Compost Council's Seal of Testing Assurance Program and were, therefore, a valuable compost product.

Land and water managers who apply herbicides to control invasive plant species and other nuisance vegetation strive to minimize environmental impacts as a matter of policy and daily operations. It is, therefore, not surprising that concern has been expressed and many questions asked relative to recent publications by Relyea (2005a, 2005b, 2005c), which implicate use of glyphosate-containing herbicides in global decline of amphibians. The purpose of this article is to put these recent publications in perspective relative to aquatic and terrestrial natural area weed management and explain why land managers should continue to use glyphosate-containing products to protect managed habitats from weeds without concern for unreasonable adverse environmental impacts.

When researchers and managers are asked to rank the issues that prevent adequate control of invasive species, lack of public awareness is at the top of the list (Dehnen‐Schmutz et al. 2018). It is therefore imperative to raise the general public's awareness of the potential risks of introducing alien species into the wild. Green Pioneers, a citizen science project funded by the Flemish Government, (Fig. 1) aims to address this issue in Belgium, across age groups. The project aims to Create awareness on invasive species, highlighting how invasions can be avoided and how to mitigate their impact. Improve communication between citizens and scientists on conservation and invasive plant species. Augment the quality and quantity of data on invasive species. Create awareness on invasive species, highlighting how invasions can be avoided and how to mitigate their impact. Improve communication between citizens and scientists on conservation and invasive plant species. Augment the quality and quantity of data on invasive species. The project is developing three kinds of activity, specifically to attract a broad demographic: - 'Young Pioneers', by developing tools for teachers in science, technology, engineering and mathemathics for school children from 12-15 years old. - 'Online Pioneers', through our online citizen science platform DoeDat.be, by helping with the transcription of label information on herbarium specimens, - and 'Visiteers', by inviting companies and working age people to help us in the collection and to inform them about invasive species. Finally, we will be organizing a BioBlitz in spring 2020 at Meise Botanic Garden where we will celebrate plants and all our Green Pioneers, while also spreading the message of invasive plant awareness. During our 48 hour BioBlitz, scientists, volunteers and citizens are workig together to survey the biodiversity of our Botanic Garden. Ultimately, Green Pioneers aim to encourage recording of alien species by amateur botanists and create a generation of responsible gardeners who understand the consequences of releasing invasive alien plants into the wild.
