Planting plants, growing understanding, nurturing passion.

Peter Bowler

Most of these students have never been to a wetland, never been to a river..it’s exciting to awaken these feelings.

Dr Peter Bowler is a Senior Lecturer in Ecology and Evolutionary Biology at University Calfornia Irvine. His is Director of the UCI Arboretum and Herbarium, is Faculty Manager of the Natural Reserve System’s San Joaquin Marsh and Burns Pinyon Ridge Reserves, and Director of the Interdisciplinary Minor in Global Sustainability.

Extra: Field-trip to the San Joaquin Marsh.

Talking points

I grew up by in Idaho by the Snake River, and I worshipped nature, botany, I loved freshwater biology, It stimulated me. I became very interested in snails.

I managed to get four snail species listed as endangered, I was involved in a lot of dam controversies, even described a new new genus and species in one of them.

When I was a child, it was so remote, my parents were educated luminary people in the area, so every geologist and palaeontologist passing through would stay at our house.

My role has been primarily teaching, I ran an environmental education programme here at UCI

I teach a lot, a lot more than I’m required to teach, but I enjoy teaching.

(Developed a sustainability minor in 1994 only a couple of years after Rio) Before that I was involved in global peace and conflict studies – they’re very similar. One of the things I really about both programmes is the interdisciplinarity that is emphasised – the fact that cooperation, complementarity and hearing what other people have to say…learning about other fields is very important.

One of the most exciting things is the establishment of a formal initiative in sustainability.

Ecological restoration…a massive expansion locally…I was involved in a lot of controversy.

America was a leader in environmental ethics – we need to return to that.

The original idea was conquering the west, trying to be master of nature, fighting nature, trying to control it, bringing it into utilitarian causes. And then there came a time when the American consciousness changed, people thought maybe we’ve gone too far, we need to start setting land aside, we need to start going the other way – preserving things. Modern attitudes about desert are very different from what they used to be – it used to be they were viewed as wastelands, today people treasure them.

There’s a need for cities not to be ecological deserts.

People are realising that deserts have an intrinsic value unrelated to people, and that’s a very different kind of epiphany.

Most of these students have never been to a wetland, never been to a river..it’s exciting to awaken these feelings.

You want to teach the intrinsic value of these sites – my this an area that has 273 bird species, I never knew that. Here is an area of 55 hectares of wetland that Dr Bowler and his colleagues got funding for, designed and constructed – for us and for wildlife..and if he can make a difference, I can too.

Ethical structures…land ethic.

Understanding expressions of culture has adopted. Compare the intrinsic values expressed in the Wildlife Act to a time of shooting buffalo from the train.

One of the wonderful things about sustainability at this point in time is that we can look back – we never should have built all those dams…

Sustainability: we share the planet with other organisms, and as the human population expands, and so do its needs and requirements, we have to do that in a way that does not further degrade – to the extent possible – the natural environment in which we live.

We are cohabiters with nature and life.

In my classes…(even the theory ones)…students go and plant plants.

Our urban landscapes are not restoration sites, but they can play a large role, particularly in softening the impact along the urban/wildland interface… and in providing corridors.

Restoration can’t be pure restoration everywhere, most places have been so severely damaged that you’ll never get the full complement of species, and the true goal of restoration is to do that – to bring back all of the biodiversity that existed at site using a natural model. Then ameliorating the impact of humans along the line. Expanding and connecting natural areas.

There are efforts to scale things up. While I was talking before about pure restoration maybe not being possible, it’s all worth trying. It may not be like it was when native Americans were here, but it can definitely be wild.

To me, to really be meaningful we should focus on expanding our natural areas and connect them…then native plants in urban areas to connect

It’s just about planting plants, it takes landscapes too. Today we’re going back…putting bends in the river…developing ways to hold water on the site rather than getting rid of it.

(Are roof gardens, community gardens, small scale restorations worth the effort?) Absolutely. Placement is important, but they are extremely valuable in educating students, they’re integral in having places for both resident and migratory wildlife, critical for linking habitats.

(Success) Area has had a history of grazing…the cattle had really bashed it…working with agencies I was able to get 12.5 acres preserved. We transplanted…native species…to remove non-natives, replace it with native known genetic stock, now besides the California gnatcatcher which is abundant there, there is the California coastal cactus wren which is almost extinct – and we have several pairs nesting in the cacti we have moved.

(Activist) Yes. I certainly have been in the past. Not so much marching and carrying billboards, as trying to provide sound scientific comment on management approaches, publishing, training. I consider teaching activism. Training students to be able to understand and think critically on their own.

(Motivation) I have a ridiculous number of everything to do. 748 students this past quarter. Every day I go to the marsh, and all the coyotes – we all know each other, they see me coming, we sort of salute each other, I howl at them a little bit – for me personally this has been beautifully fulfilling in my lifetime. I can show you picture of areas that had not a plant on them, and now is healthy coastal sage scrub with gnatcatchers living underneath it – I can’t tell you how rewarding that is.

(Challenges) Follow-up restoration…we have just completed removing 3,100 lineal feet of road,…my ultimate plan is to make the lower part of the marsh an area that salt marsh can migrate into, before flood control channelisation in 1968 you could row from Newport Back Bay and all the way up into the marsh…so I would to open it, so when sea level rises and we lose that 900 acres of salt marsh, we’ll be able to at least have 50, maybe 100 acres for the salt marsh for the highly endangered Ridgway’s rail. Its a salt marsh obligate, unless we do this it will go extinct. It’s very important, I’m going to get that done.

(Miracle) In the marsh it would definitely be developing the whole lower marsh as a salt marsh. I’d like to do a study of the succession that will occur as the relationship shifts between the landscape and the Pacific Ocean. In education it would lower class sizes, more interactive hands-on learning approaches will be more meaningful.

(Advice) We need to be more cautious and think really about our personal…karmas…behaviours. When I came to California in the 1970s there was so much smog, your couldn’t even see across the campus. And thanks to catalytic converters and other improvements, that’s gone. We can be little catalytic converters as well. We can make huge contributions as an individual among a larger group. I think that’s something people forget – they think “gosh, it’s too much, there’s no impact I can have”, but you can have. And it’s not just an impact for the environment, or society, it’s an impact for you. You can be personally empowered. You can be fulfilled. You can have huge reward as you work with others, share with your family – this is probably the most meaningful thing of all – is your own inner light.

This Sustainable Lens is from a series of conversations at University California Irvine. Sam’s visit was supported by the Newkirk Center for Science and Society, and coincided with Limits 2015.

Interdisciplinary ecological restoration

Bruce Clarkson

The problems of degradation are not just the sole domain of biophysical scientists.

Professor Bruce Clarkson is Dean of the Faculty of Science and Engineering at the University of Waikato, and is the Interim Director of the Biological Heritage National Science Challenge. He is recognised as one of New Zealand’s foremost authorities on ecological restoration. We talk about his background, what we learnt from island and mainland sanctuaries, and the opportunities and challenges of restoring ecosystems in urban environments.

Talking points

Most people don’t experience nature in a way we did in previous generations

How might you restore indigenous nature in an environment where people can access them more easily?

New Zealand has extremely high levels of endemism…if we don’t look after these native plants and animals, no one else is going to do it…this is our responsibility.

This is our biological heritage, this is what makes NZ special and different, it’s our responsibility as stewards of the land to maintain our natural heritage.

What you are really trying to do is manage the whole system, but a focus on birds will have positive spinoffs for the rest of the ecosystem

So what you are trying to achieve in the longer term is a recovery of the whole system, not just the bird populations.

It has to be a mix and match of approaches and a portfolio of places.

We’re working for the very long term so we have to build resilience into the system.

If we don’t do it, we will be responsible for the extinctions because we brought in the agents of change.

If we protect species, we protect their house.

We can treat our native birds as the umbrella species for the whole system that we’re trying to maintain, protect and restore.

Cities have some advantages over wildlands in terms of protecting native plants and animals…just think of the example of grazing animals.. you don’t have to confront the problems of goats and grazing cattle.

Looking after your own backyard and being a steward of something you cherish.

Start at a scale you can manage, have a plan and progressively recover what you are trying to achieve.

You can make big mistakes, the classic mistake people make in gully restoration is that they bite off more than they can handle.

I tend to be an optimist. Yes, there’s a lot of negative out there, and there’s a lot of degradation of the environment still going on. It would be an interesting research question, what would be the threshold point at which recovery tipped the balance back to the point where there was more improvement going on than degradation? I think in some points in our region we are very close to that threshold. Overall it is still a fact that New Zealand is still losing things. Forests are being cleared, wetlands are being drained, nowhere near the rates they were previously when we were in the land development phase, but some of that is still going on. There are large parts of the Department of Conservation estate where there little active management is occurring, and those areas are also going backwards. But the point is that there are significant areas where we are making a difference. So I see it in a more optimistic way. Know also, that we do have the technologies to do more and more of this restoration, it’s really a question of how much time, effort and funding is New Zealand as a nation prepared to put into it to get us to the threshold of recovery at regional and national scale.

We’re trying to bridge the interdisciplinary gaps.

The point is how we deal with interdisciplinary problems.

The problems of degradation are not just the sole domain of biophysical scientists. To get the results that you want you need expertise in a wide range of areas. This is another advantage of working in urban areas, there are a lot of professions, all with interests in how we might restore urban environments.

We want engineers who not only know about engineering, but know about the environment as well.

I think the solutions to most (environmental) problems are actually about how we build bridges between the different disciplines…to come together and work collaboratively.

Increasingly, graduates from university are expected not just to know about their discipline, they are expected to work in multidisciplinary teams, on projects where people are trying to achieve solutions to particular problems.

It’s not just about a technical fix, it’s about understanding how you can do things in different ways, often the ways things use to be.

Restoration ecology is difficult, reconstructing an ecosystem takes time, but if you go into it knowing that and how the system works, you can make a long term plan for restoration, a plan for a process that might be inter-generational.

A 500 year plan, with milestones along the way

Once you’ve started a project, once you see process, people take pride in the process. It’s quite inspirational what a change you can make on the landscape in such a short time.

(Activist?) People who work in universities in many respects are people who love ideas, and love the debate around ideas – and if that is what an activist is, then essentially that’s what you are. You’re looking at systems, you’re understanding the system, and you’re trying to pass on your knowledge of how best to manage that system in an effective way. If that is what an activist is, then that’s what you are.

(Motivation?) Students, seeing the progress my students make, and where they end up. Being able to contribute to knowledge and process. The process of protecting and restoring plant communities and the animals that go with them – for some reason as a child that gelled with me, and I’m still passionate about achieving the same thing. Making a difference.

(Challenges?) Staying fit and healthy and keeping going.

(Miracle?) A silver bullet for pest control. Some new way that is socially acceptable for controlling mammalian predators that prey on our native birds. That would very rapidly and radically alter our landscape.

(Advice?) Look around your own neighbourhood, find out who are the people doing this sort of work and go along and give them a hand because they need all the help they can get.
