title: Stakeholders’ views on the global guidelines for the sustainable use of non-native trees

description: A large number of non-native trees (NNTs) have been introduced globally
 and widely planted, contributing significantly to the world's
 economy. Although some of these species present a limited risk of
 spreading beyond their planting sites, a growing number of NNTs are
 spreading and becoming invasive, leading to diverse negative impacts on
 biodiversity, ecosystem functions, and human well-being. To help minimize
 the negative impacts and maximize the economic benefits of NNTs, Brundu et
 al. developed eight guidelines for the sustainable use of NNTs
 globally—the Global Guidelines for the Use of NNTs (GG-NNTs). We used an
 online survey to assess perceptions of key stakeholders
 towards NNTs and explore their knowledge of and compliance with
 the GG-NNTs. This dataset includes the results of such a questionnaire.
description: The questionnaire was comprised of three sections: (1) a section
 aimed at assessing how respondents perceive NNTs, (2) a section designed
 to assess whether stakeholders comply with the GG-NNTs, and (3) a section
 aimed at collecting sociodemographic information about the respondents and
 their institution. The questionnaire was distributed amon 753 identified
 relevant stakeholder institutions, divided all identified into seven
 groups according to the sectors they can be associated with: (1)
 aesthetics, (2) environmental improvement, (3) research in forestry, (4)
 forest industry and forest production, (5) research in nature
 conservation, (6) nature conservation, and (7) other, those that did not
 fit any of the other categories (e.g. environmental consultancies and
 governmental agencies).

 data and file structure **Data were obtained from a questionnaire (see
 Questionnaire.pdf)** #### File: Data\_Dryad.xlsx **Description:** Data
 collected from a questionnaire Participants were required to answer all
 the questions. We only registered responses from participants working
 within organizations that are involved in one or more of the following
 activities: studying, planting, using, or managing NNTs. Overall, the data
 includes: Column A: ID given to each respondent Column B. Respondents were
 asked whether they had heard of non-native trees before. This column
 includes the answers (Yes or No). Columns C-E: Respondents were asked to
 think about the first three words that spontaneously come to mind when
 they think about non-native trees and to rate these words as something
 very negative (-2), negative (-1), neutral (0), positive (1) or very
 positive (2). Only the ratings for these three words (i.e., not the words)
 were kept. Columns F-S. Respondent's agreement or disagreement (on a
 likert scale) with a series of statements to a series of statements.
 Columns T-AC: Answers to the questions on whether stakeholders are
 complying with the Global Guidelines for the sustainable use of Non Native
 Trees  Columns AD-AJ: Socioeconomic characteristics of respondents
