Challenges and trade-offs in the management of invasive alien trees

Biological Invasions, 2013

Over 430 alien tree species worldwide are known to be invasive, and the list is growing as more tree species are moved around the world and become established in novel environments. Alien trees can simultaneously bring many benefits and cause substantial environmental harm, very often leading to conflicts over how they should be managed. The impacts grow over time as invasions spread, and societal perceptions of the value of alien trees also change as understanding grows and as values shift. This leads to a dynamic environment in which tradeoffs are required to maximise benefits and minimise harm. The management of alien tree populations needs to be strategic and adaptive, combining all possible management interventions to promote the sustainable delivery of optimal outcomes. We use examples, mainly from South Africa (where issues relating to invasive alien trees introduced for forestry have received most attention), to argue for holistic and collaborative approaches to alien tree management. Such approaches need to include bold steps, such as phasing out unsustainable plantation forestry that is based on highly invasive species, and in which the costs are externalised. Furthermore, it would be advisable to impose much stricter controls on the introduction of alien trees to new environments, so that problems that would arise from subsequent invasions can be avoided.

Everglades Invasive Species Special Issue: Introduction and Overview

Southeastern Naturalist, 2016

This broad category covers the interface between government programs and private action. It includes, for example, technical assistance and incentive programs to encourage invasive species control on private lands. Government sponsored public awareness campaigns and the development of industry partnerships and "codes of conduct" are other examples. These programs and authorities build the government's capacity to deal with invasives by changing prevailing beliefs and behaviors and by enlisting private activity in a broader campaign. CHAPTER 1 9 5) Strategic Planning and Coordination. This category encompasses efforts to bridge gaps between local, state and federal agencies and to set priorities and strategic goals across jurisdictions. Coordinated responses and agency partnerships maximize government resources, avoid redundancy, and drive innovation. Interagency cooperation and strategic planning are particularly important in Florida, given the federal government's leadership in South Florida Ecosystem Restoration. ORGANIZATION The report is organized as follows: The Federal Legal Framework. This initial section lays out the primary federal authorities that relate to prevention and control of invasive species. As will be explained further, the United States lacks a comprehensive statutory framework for invasive species, and many relevant provisions reside exclusively in agency policies and regulations. This section highlights the fundamental federal authorities in the area and points out the major gaps and weaknesses. The unusual fusion of federal and state authorities driving South Florida Ecosystem Restoration is an important part of Florida's legal landscape, and is also described in this section. Ecosystem Restoration Authorities and the State Role. This section briefly describes the network of interrelated federal and state ecosystem restoration authorities that overlay traditional invasive species authorities in Florida. The analysis outlines how government agencies are using their authorities to address invasive species in Florida, particularly with respect to Everglades restoration. Included in this section are state and local programs which put the federal role in context and highlight gaps in government responses. Gaps and Conflicts Analysis. This section presents the weaknesses, gaps, and conflicts in the fabric of invasive species authority in Florida and emphasizes practical issues of implementation. Most deficiencies were initially revealed through conversations with professionals working on a full spectrum of invasive species issues in Florida. State and federal authorities and programs are analyzed together in order to bring into focus specific areas where existing laws and regulations are inadequate (gaps in authority), situations where agencies could be doing more to fully exercise the authority available to them (gaps in implementation), and examples of direct conflicts and inconsistencies in the legal framework.

Conflicting values: ecosystem services and invasive tree management

Biological Invasions, 2014

Tree species have been planted widely beyond their native ranges to provide or enhance ecosystem services such as timber and fibre production, erosion control, and aesthetic or amenity benefits. At the same time, non-native tree species can have strongly negative impacts on ecosystem services when they naturalize and subsequently become invasive and disrupt or transform communities and ecosystems. The dichotomy between positive and negative effects on ecosystem services has led to significant conflicts over the removal of non-native invasive tree species worldwide. These conflicts are often viewed in only a local context but we suggest that a global synthesis sheds important light on the dimensions of the phenomenon. We collated examples of conflict surrounding the control or management of tree invasions where conflict has caused delay, increased cost, or cessation of projects aimed at invasive tree removal. We found that conflicts span a diverse range of taxa, systems and countries, and that most conflicts emerge

Standardized invasive species terminology for effective education of Floridians

EDIS

In this document we introduce a standardized set of seven terms compiled by the members of the UF|IFAS Invasive Species Council that can describe most situations involving invasive species. We do so to promote a common language among Florida’s Extension and outreach professionals. This will limit confusion caused by excessive jargon used to describe invasive species and the fact that much of this jargon is used incorrectly. This confusion hinders stakeholder understanding of environmental and economic impacts caused by invasive species which can prevent stakeholders from adopting behaviors that can both limit the introduction of new invasive species and decrease the impacts of those already established. The seven terms we propose are “native”, “nonnative”, “introduced”, “established”, “invasive”, “nuisance”, and “range change”. We also list six terms to avoid due to their tendency to create confusion and/or be misused and misinterpreted (“native invasive”, “invasive exotic”, “invasi...
