How is Restoration Relevant to Stewardship?

Can Landscape Stewardship really include restoration? Even more the concept of novel systems and their management? The upcoming workshops on the implementation of the European Landscape Convention in October have the sub-title “the landscape knows no boundaries”. That is true, but it is as true in time as it is in space, and that’s where restoration, and management of novelty, become important….

At the turn of the century Jessica Brown and Brent Mitchell (2000) described Landscape Stewardship as “usually thought about in terms of the essential role individuals and communities play in the careful management of our common natural and cultural wealth, both now and for future generations”. This was more contemporaneously expressed by Jianguo Wu (2013) as a “place-based, use-inspired science of understanding and improving the dynamic relationship between ecosystem services and human well-being in changing landscapes”. Both of these views strongly emphasis the role of people in landscapes, as key elements of their stewardship. Wu’s quote also embraces the ecosystem service paradigm more familiar in the second decade of the century, whereas the earlier quote emphasises natural and cultural wealth. But all seems linked to the maintenance of landscapes as they are, although Wu does use the word dynamic.

So what’s the relevance of restoration in stewardship? Simply put; we are no longer able to just “preserve” landscapes (or biodiversity at finer scales) as if they were Jams and Marmalades, as Gary Larson (1989) once wickedly suggested!

Landscapes which are degraded do have enormous potential for restoration, but it is often thought that intervention in landscapes now dramatically altered from their “natural” state needs to take into account both their current status and the potential effectiveness of traditional conservation or restoration measures (Richard Hobbs and colleagues, most recently 2014). In this context we should be broadly aware that:

  • Biodiversity can enhance the resilience of landscapes to environmental changes;
  • Biodiversity is changing across many different taxonomic groups and biomes as a result of recent environmental change;
  • Effective sustainable management requires understanding of the ecological, cultural and social dimensions and requires coherent policies at all levels of government;
  • Policy options include community-based projects, carefully designed restoration projects, and/or appropriate management of novel ecosystems, economic incentives combined with public participation, and effective monitoring and enforcement.

Restoration is often viewed as returning a landscape or ecosystem to a previously functioning “natural” state. Yet more and more this is impossible, as landscapes are increasingly a matrix of ecosystems or “biodiversity patches” modified in various ways from an observed, or frequently presumed, original state. This landscape matrix, although it may be ecologically sub-optimal, can, and does, deliver a range of ecosystem goods and services; for people, but also for adjacent landscapes/ecosystems.  It should also be recognised that landscapes which have been changed can either “self-restore” or move to a new state, depending on the prevailing ecological conditions. Management challenges and opportunities presented by these landscape matrices encompass how the degree of modification affects broader-scale processes e.g. eco-hydrological activity, gene flows, cultural perceptions and interactions, animal movements between adjacent or far-distant landscapes etc.

Some landscapes which look (and are appreciated) as natural today are in fact restored or reconstituted. The Isle of Man has many National Glens, which are well forested, and most visitors and many locals see them as natural. Yet most have been deliberately restored to wooded valleys during the early part of the C19th, to attract tourists. A minor consequence has been that such afforestation (often with species that may have been present, or maybe not), has allowed the rich bryophyte and lichen flora to flourish. The photograph (© Peter Bridgewater) is from Groundle Glen, showing the dense understorey – and a surprise component in Cordyline australis- widely grown in gardens across the island, but here established, apparently adventively.

All this means any stewardship plan for such landscapes must include inclusive development of conservation, restoration and management strategies that comprehend rapid spatial and temporal change, and reflect the complexity of the current landscape patterning. Which brings us back to the definition of landscape stewardship quoted at the outset – stewardship is very much about management, recognising that change is inevitable, and embracing and managing for change where that seems preferable to simply leaving things as they are. Above all using restoration as part of landscape stewardship is also about being prepared for surprises and adapting to the new, while valuing the old, where it is still sustainable so to do.

This blog contribution is used with the permission of  Hercules a project to empower private and public actors to protect and sustainably manage cultural landscapes. It is part of a series on the science and practice of landscape stewardship and will be further elaborated in the course of a book chapter. We are looking for real-world cases of good practices that exemplify the principles of landscape stewardship and that serve as a model to inspire implementation in other landscapes.
