The paper presents opinions of local government authorities on determinants of local entrepreneurship development. The research conducted in 2017 in rural and urban-rural municipalities of Warmińsko-Mazurskie Voivodship (Poland) shows that among the locational conditions for entrepreneurship development the tourist attractiveness was rated as the highest. Infrastructural conditions were assessed as favourable while such features of the residents as education level, age or qualifications were satisfactory for the respondents. Protected natural areas, popular in the analysed region, were both a barrier and an opportunity for entrepreneurship development. Moreover, self-government activities were evaluated as good on the local level, and satisfactory on the regional level.

Circular 1204-Sp, an 8-page illustrated  publication by K.A. Langeland, is the Spanish language version of Circular 1204, “Help Protect Florida’s Natural Areas from Non-Native Invasive Plants.” It describes the problem of weeds in natural areas, federal and state laws regulating plants, official lists of non-native invasive species. It encourages Florida residents to learn to identify invasive plants and to remove them from their property. Includes references. Published by the UF Department of Agronomy, February 2008.

Abstract Noronhia emarginata is a slow-growing evergreen tree native to Madagascar. The species has been introduced to several tropical and subtropical countries as an ornamental. It is widely but sporadically cultivated in tropical regions, primarily as an ornamental tree, and sometimes grown in various tropical botanical gardens. A very tough tree with a high tolerance for salt and wind, N. emarginata is well suited to coastal and seaside locations. The species has been recorded as invasive in Hawaii, but further evaluation was required based on the weed risk assessment. It is considered a highly invasive species in Bermuda, but no details on its impact are available. The species is not considered to be a weed which causes disturbance in gardens, nor does it impact any agricultural, forestry or horticultural activities. The species has not been documented in any undisturbed natural areas in Florida.

AbstractCadillo is an invasive species in Florida pastures and natural areas. Despite its invasiveness, relatively few studies have evaluated cadillo management. Thus, the objective of this research was to determine effective POST herbicides for cadillo control in Florida. Greenhouse and field studies were conducted at the Range Cattle Research and Education Center near Ona, FL, in 2015 and 2016. In the greenhouse study, triclopyr-ester, aminopyralid, metsulfuron, 2,4-D amine, aminopyralid+metsulfuron, aminocyclopyrachlor+metsulfuron, and imazapyr+aminocyclopyrachlor+metsulfuron provided ≥80% control of cadillo 28 d after treatment (DAT). Aminocyclopyrachlor at 17 and 35 g ha–1were the only treatments with <80% control, with 70% and 75% control, respectively. Similar results were reflected in cadillo dry biomass reduction. The herbicide treatments used in the field study were triclopyr-ester, aminopyralid, 2,4-D amine, aminocyclopyrachlor, and triclopyr+fluroxypyr. Most treatments provided excellent control in the field (≥90% control) 30 DAT, and by 60 DAT all treatments provided 100% control. Results from these studies suggest that cadillo is susceptible to many of the common POST herbicides utilized in pastures and natural areas in Florida.

As the human enterprise expands, the task of preserving biodiversity increasingly must be carried out in areas heavily modified by humanity ? the domain of countryside biogeography (Daily 2001; Daily et al. 2001). Countrysides normally are thought of as rural environments. The dividing line between rural and urban is often blurred by suburbs; urban environments represent the expanding end of a continuum of disturbance, the other end of which is the shrinking domain of relatively undisturbed natural areas and wilderness. Because of the growing preponderance of urbanization, ecologists over the past quarter century have increasingly turned their attention to conservation in urban areas.

Deep learning classification of invasive species using widely-used ArcGIS Pro software and increasingly common drone imagery can aid in identification and management of natural areas. A step-by-step implementation, with associated data for users to access, is presented to make this technology more widely accessible to GIS analysts, researchers, and graduate students working with remotely sensed data in the natural resource field.

AbstractSeeds play a major role in plant species persistence and expansion, and therefore they are essential when modeling species dynamics. However, homogeneity in seed traits is generally assumed, underestimating intraspecific trait variability across the geographic space, which might bias species success models. The aim of this study was to evaluate the existence and consequences of interpopulation variability in seed traits of the invasive species Carpobrotus edulis at different geographical scales. We measured seed production, morphology, vigour and longevity of nine populations of C. edulis along the Catalan coast (NE Spain) from three differentiated zones with a human presence gradient. Geographic distances between populations were contrasted against individual and multivariate trait distances to explore trait variation along the territory, evaluating the role of bioclimatic variables and human density of the different zones. The analysis revealed high interpopulation variability that was not explained by geographic distance, as regardless of the little distance between some populations (< 0.5 km), significant differences were found in several seed traits. Seed production, germination, and persistence traits showed the strongest spatial variability up to 6000% of percent trait variability between populations, leading to differentiated C. edulis soil seed bank dynamics at small distances, which may demand differentiated strategies for a cost-effective species management. Seed trait variability was influenced by human density but also bioclimatic conditions, suggesting a potential impact of increased anthropogenic pressure and climate shifts. Geographic interpopulation trait variation should be included in ecological models and will be important for assessing species responses to environmental heterogeneity and change.
