Due to the on-going Covid 19 pandemic I will not be travelling to the UAE (or anywhere) during the winter season of 2020/21. I am available to carry out remote design or consultancy for certain things, although there are limits to what can be done in this way.
Trees are complex things, and don’t always give up their secrets easily, but when considering what needs to be done, there are tell-tale signs to look for. I can often spot these remotely if provided with good quality pictures and video.
I can remotely advise on the design, selection and placement of trees and other landscape elements.
What is harder is working with contractors to ensure that they know how to prune correctly – most, unfortunately, do not and the majority of inquiries I get are on this subject. In the past, I have worked to train contractors in the correct use of tools and pruning techniques, but this is only viable on larger projects.
I am happy to work with you remotely as far as is possible! Please contact me by email, phone or WhatsApp to discuss your needs.
If you need help or advice with your trees, I will be visiting Dubai for the week of February 23rd, advising on trees for private and commercial clients. If you have a tree you need help with, or a developments project with trees involved, I have a few appointments available.
Landscapes are all about creating micro-climate, or would be, if designed for that goal. Why is this important and what do I mean?
Almost all life is contained in a thin crust of soil, a wedge of atmospheric gases, and water. Plants are the principal medium that interacts with and regulates all three. Absolutely nothing else does this as well, or at all; think about it.
The way we organise our plants in our urban landscape will determine how well this interaction occurs, how successful it is. Yet I have never heard of a single project that has been developed with this understanding and this goal in mind. With climate change, we urgently need to re-think the way we design our landscapes, and why we design them. Whilst all the human-centric design reasons will always hold true, we need to layer into our thinking this new understanding of how plants interact. To build new ecologies, new ecosystems, we have to design for plants to actually function, rather than just look nice. For when they do this, our environment literally comes alive. More importantly, they might just, if done on sufficient scale, save us from ourselves.
When I use the word treescapes, I don’t just mean trees and grass; we’ve had that for years in the form of parks, and in their traditional form, they’ve done little for us. No, our designs need to build up layers of living material – biomass, for with biomass comes moisture entrapment, shade, food for insects, etc. Think of it in terms of height and depth of microclimate. How much depth is there in a stretch of irrigated grass, maybe 50mm above ground, 200mm below? No species variation, so what we have is little more than a green desert, albeit one that can hold bit a of moisture.
Trees in paved streets are also less able to generate micro-climate, but they are a bit of an exception, as they provide shade for people to walk under. Where width allows, even here we should layer our planting.
If we replace that grass with a range of groundcover plants – not a monoculture – you begin to get a little more variation; different root structures and depth, different foliage shapes, height, form and flower. More variety, more microclimate, more food source, more ecology. Looks good too.
Next we add shrubs and suddenly we are into an new realm, that of woody plants (I’m being simplistic here, many groundcovers are of course woody). Shrubs create three-dimensional space with their frameworks, within which micro-worlds reside. Deciduous plants shed their leaves, as do evergreens, and this begins to build leaf litter – mulch. Don’t tidy it up! We need ecologies in that soil, and microbes need food. Our obsession with tidyness has a lot to answer for. Suddenly, we have height in our micro-climate, three-dimensional form. We humans (for we scale everything according to our own height and perception) can walk amongst these plants, take part, interact. Our microclimate is now two metres high, maybe more. But something is missing and it’s still too hot…
Trees! Now we have a game changer and our micro-environment just became vast, in relative terms, maybe up to 30 metres, though 10-20m may be more average. We now have true diversity of shape, height, leaf, flower and roots. We have shade! Under trees it may be 10°C cooler and we love it. Plants love it too. Moisture now gets retained within the human habitable zone, fungi and microbes thrive in soils, insects and birds abound. This is our urban jungle and we need it. The planet needs it. This tiny sliver of crust we live on can be rich, abundant, in every climate and every place, if we put our minds to it, if we have the will. And when the planet becomes searing, creating livable environments with trees of any type, may be the only thing that keeps us alive, unless we become troglodytes.
This is the next level of landscape design, the new challenge; creating future ecologies and environments that matter, that keep us cool, that give us resources and soothe our souls. We will create new (novel) ecologies that fit the changing environment, trans-migrating parts of ecologies that once lived elswhere. In that place they may be dying out, as might your local ecology. If they now fit where you live, that’s where they need to be. In turn, that place of origin may itself need to adapt and change. In all things and all places, we need microclimate, shade and soil.
Are you up for it? I am!
On my last few trips to Dubai, I have been noticing a lot of trees with lighting installed in them. Whilst these can create stunning effects at night, the correct methods of installation and maintenance are essential for the long-term well-being of the tree. We have to put the needs of the tree first – if the light effects are more important, then just don’t use a tree! Much of what I have seen – and this applies world-wide, not just in the UAE (I have seen equally bad wiring in the UK, Chicago, etc.) – is messy and very likely to cause long-term damage to the tree, if it doesn’t kill it entirely.
We have to reconcile the fact that trees expand in girth year on year (including palms, though in a different way) through what is termed secondary growth. All this growth happens in the region just under the bark in the cambial layers and produces new meristematic tissue. Damage or restrict this layer and it effects the whole health of the tree. Cable ties are like a choke collar to a tree; as it grows it gets choked. Many trees will solve this by growing over such a restriction but this can leave the wood vulnerable to infection and mechanical stress. Likewise, light mounting brackets screwed directly onto a tree become overgrown and are again a source of potential infection.
If the aim of lighting is to create an aesthetic effect, it should not be at the expense of the trees aesthetic, nor of it’s health. I can’t imagine that the lights above look very good at night, although i wasn’t there to see them on.
There is a correct way to do all this and keep the tree in good health (as far as any interference can be healthy). If you have such a project, either existing or potential, please contact me to discuss assistance in achieving best practice.
