Spatial Dispersal

Invasive plant species have adversely affected rangelands throughout the world and continue to invade previously uninfested lands at an alarming rate. Previous efforts have focused on eradication and control; however, recent efforts have recognized that preventing invasive plant species from infesting new areas is more cost-effective and efficient than trying to restore the system after it is infested. One of the major components of prevention is limiting the introduction of the invasive plant to uninfested areas. Guidelines to limit the introduction of invasive plants into new areas are usually general and not developed to address differences in dispersal vectors among invasive plants. To limit the dispersal of invasive plants, land managers need a framework that assists them in identifying major spatial dispersal vectors and management strategies based on those vectors. We propose an initial conceptual framework that integrates the ecology of invasive plant dispersal with prevention management. The framework identifies major potential vectors by incorporating invasive plant seed adaptations for dispersal through space and infestation locations relative to vector pathways. The framework then proposes management strategies designed to limit dispersal by those specific vectors. The framework ALSo identifies areas where research could improve the effectiveness of dispersal-prevention strategies by providing additional management tools.

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.

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

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.

Invasions of aggressive alien plant species that have a high rate of expansion and pose a threat to ecosystems and their biodiversity have become more active in the 21st century due to anthropogenic disturbances of vegetation cover, the lack of systematic control of their numbers, the expansion of transport corridors, etc. Research for the search of new locations of adventitious plant species is carried out in the Republic of Bashkortostan especially intensively during the last 10 years. The result of this work was the publication of the "blacklist" flora of Bashkortostan [1] including 100 invasive and potentially invasive plants and "Synopsis of adventive species of the Republic of Bashkortostan" [13], who presented data on 457 localities of alien plant species, is not peculiar to the nature of Bashkortostan. This article is an addition to the previously published data obtained during the route expedition research in 2019-2020, conducted in the Western regions of the Republic. More than 150 new localities of 22 invasive and potentially invasive plant species were identified. 11 species are included in the “Black book of flora of Central Russia” [9]. The data obtained clarify and expand the understanding of the modern secondary range of invasive plants on the territory of the Republic.

Protein Sources

Agriculture has come under pressure to meet global food demands, whilst having to meet economic and ecological targets. This has opened newer avenues for investigation in unconventional protein sources. Current agricultural practises manage marginal lands mostly through animal husbandry, which; although effective in land utilisation for food production, largely contributes to global green-house gas (GHG) emissions. Assessing the revalorisation potential of invasive plant species growing on these lands may help encourage their utilisation as an alternate protein source and partially shift the burden from livestock production; the current dominant source of dietary protein, and offer alternate means of income from such lands. Six globally recognised invasive plant species found extensively on marginal lands; Gorse (Ulex europaeus), Vetch (Vicia sativa), Broom (Cytisus scoparius), Fireweed (Chamaenerion angustifolium), Bracken (Pteridium aquilinum), and Buddleia (Buddleja davidii) were collected and characterised to assess their potential as alternate protein sources. Amino acid profiling revealed appreciable levels of essential amino acids totalling 33.05 ± 0.04 41.43 ± 0.05, 33.05 ± 0.11, 32.63 ± 0.04, 48.71 ± 0.02 and 21.48 ± 0.05 mg/g dry plant mass for Gorse, Vetch, Broom Fireweed, Bracken, and Buddleia, respectively. The availability of essential amino acids was limited by protein solubility, and Gorse was found to have the highest soluble protein content. It was also high in bioactive phenolic compounds including cinnamic- phenyl-, pyruvic-, and benzoic acid derivatives. Databases generated using satellite imagery were used to locate the spread of invasive plants. Total biomass was estimated to be roughly 52 Tg with a protein content of 5.2 Tg with a total essential amino acid content of 1.25 Tg (~24%). Globally, Fabaceae was the second most abundant family of invasive plants. Much of the spread was found within marginal lands and shrublands. Analysis of intrinsic agricultural factors revealed economic status as the emergent factor, driven predominantly by land use allocation, with shrublands playing a pivotal role in the model. Diverting resources from invasive plant removal through herbicides and burning to leaf protein extraction may contribute toward sustainable protein, effective land use, and achieving emission targets, while simultaneously maintaining conservation of native plant species.

Abstract Consumers were surveyed at the 2004 Philadelphia Flower Show in Philadelphia, PA, from March 8–10, to quantify their attitudes and behaviors towards invasive plant species and potential problems associated with purchasing and planting them. A majority of the 341 participants (81.5%) was aware that non-native plants were used in the landscape and that these plants may be invasive in natural areas. Less than half (40.1%) acknowledged owning plants considered invasive while one third (33.5%) did not know if these plants were growing in their landscapes. Less than half (41.3%) believed that laws should be passed to prevent the sale of non-native plants while 27.8% believed that laws should be passed to allow sale of only native plants in their area. Three distinct consumer segments were identified using Cluster Analysis: ‘Invasive savvy,’ participants knowledgeable about invasives and interested in alternative species; ‘Invasive neutral,’ participants neutral in their decision to purchase alternatives to invasive plants and price sensitive about paying more for plants tested for invasiveness; and ‘Invasive inactive,’ participants were not price sensitive to paying more for plants tested for invasiveness, however, they appeared to oppose the purchase of plants previously listed as invasive which would be available as seedless through breeding and natural selection or other forms of genetic modification. Survey results indicated that media sources (e.g., television and print media) would be effective for educating consumers about potential problems associated with invasive species in the landscape.

Abstract In recent years, programmes aimed at improving environmental conditions in river valleys within urban spaces have been initiated in many of the European Community countries. An example is the project “Revitalization of Urban River Spaces – REURIS” which was implemented in 2009-2012. Its main aim was to revitalize a part of the valley of the River Ślepiotka in Katowice. One of the tasks of the project was a comprehensive treatment to combat invasive plant species occurring in this area, carried out by using a combination of chemical and mechanical methods. Chemical treatment involved the application of herbicide mixtures, and mechanical treatment included, among others, mowing and/or removal of the undesirable plants. The work focused primarily on reducing the spread of two species of the Impatiens genus: I. glandulifera and I. parviflora, and the species Padus serotina, Reynoutria japonica and Solidago canadensis. Currently, the maintenance works on this section of the river are performed by the Urban Greenery Department in Katowice, which continues the elimination of invasive plants, according to the objectives of the REURIS program. In 2012 the Department of Botany and Nature Protection at the Faculty of Biology and Environmental Protection started to monitor the implementation and the effects of the implemented actions for elimination and participated in the action of removal of selected invasive plant species: Impatiens parviflora and Reynoutria japonica within specific areas. These actions led to a reduction in the area occupied by invasive plants and a weakening of their growth rate and ability to reproduce.
