Why are we opening a Special Issue of Remote Sensing on the assessment of Trees Outside Forests (TOF)?
The answer is simple: it is generally acknowledged that trees have important economic and ecological functions—and we find trees not only in but also outside forests, both on natural and managed lands. The interest in TOF has actually been increasing constantly over the past decades both from a resource point of view and from an ecological perspective.
However, while there are many global and large area studies on forest cover, there does not appear to be many such studies on TOF. For example, Zomer et al. (2016) provided a global estimate for one type of TOF, agroforestry systems, and Schnell et al. (2015a) compared estimated national level forest and non-forest tree biomasses from FAO-assisted national forest inventories in 11 countries, where trees were both recorded on forest and non-forest lands. From these studies, the overall relevance of TOF became very obvious, although regionally considerably different. Publications on approaches that deal with the specific characteristics of the scattered, sometimes scarce resource TOF, are not abundant (e.g., Kleinn 2000, Schnell et al. 2015b) and do not focus on the potential of recent developments in remote sensing.
The planned Special Issue of Remote Sensing focusses on remote sensing to support the assessment of TOF. Contributions on any challenge in that context are welcome: purely technical remote sensing issues, issues of field sampling, modelling, harmonizing definitions, defining specific objectives, combination with other forest or landscape inventories, etc.
Interested authors are encouraged to submit their original manuscripts in the context of the assessment of TOF. We kindly ask the authors to carefully and explicitly explain in their manuscripts the definition of “forest“ that they apply – from which the definition of “TOF“ automatically derives. It is certainly helpful to illustrate with examples the “class of TOF“ considered for the assessment.
Please take into account that we are exclusively dealing here with biophysical definitions of “forest” (please refer, for example, to the definitions in the FAO forest classification, which base essentially on the criteria “minimum crown cover”, “minimum area”, “minimum height at maturity in situ” and “absence of other land uses than forest”), and explicitly not with legal definitions or general geographical definitions of land use classes.
We look forward to receiving your submissions.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Remote Sensing is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
