I received my placement with Kent Enterprise Trust through the employability points scheme at the University of Kent. I chose to accept the placement offer over others because I was keen to gain some knowledge in environmental work after completing my degree in Biomedical Science. My job title has been Environmental Champion, which seemed perfect for the experience I was looking for.
My first two days were spent in the Kent Community Oasis Garden, where I was given the freedom to complete my own project. Inspiration for my project came from research that I had carried out beforehand and the presence of materials in which I saw potential to be recycled into something environmentally friendly – an insect house. Insect houses encourage biodiversity, certain insects that eat pests in the garden and sometimes pollinators. It therefore, seemed beneficial to create an environment where insects that may increase the yields of the garden can live and breed.
On the first day, I lead two volunteers to collect and assemble the materials needed for the base and structure of the house. It was very rewarding to take my own initiative and guide a group to begin a completely new project. There were no volunteers available to help me on my second day so I completed the rest mostly by myself. I collected rotting wood, bark, bamboo, grass cuttings, leaf litter and other organic materials from all around the garden to arrange in the four layers of the insect house. This meant that whilst I was recycling, I was also tidying the garden a little and removing unwanted items from it. As the structure required hammering nails and sawing wood, I had to learn some new DIY skills. This was also extremely rewarding, as it was the first time that I had carried out any task like this and so it was beneficial for my life-skills and knowledge. I was really happy with the final result and I think it will very likely attract the right insects to help the garden. The volunteers in the garden seemed interested in the insect house and many of them asked me questions and wanted to know about how and why I was building it. I think this is another reason why my project was useful, as it engaged the people that it will hopefully help and raised some awareness of the importance of the ecosystem in the garden.
I spent some time in the office writing up a report for my insect house project. Researching the subject and documenting my work in this way was a useful experience. My report will be used on the charity’s website and used as an example of the benefits the garden has. The fact that my project can be an example of the great work the charity do is very satisfying. The rest of my time was spent organising and packing books for a book sale during a yearly celebration. The funds raised will be used for the community garden.
Overall, my time at Kent Enterprise Trust was productive and valuable and I feel like I have really developed my DIY, leadership and teamwork abilities. I was warmly welcomed into both the garden and office environments and enjoyed discovering how a charity runs and how that affects the beneficiaries. My wish to gain some insight into work involved with the environment was also fulfilled. The experience was rewarding and I definitely feel as though I am more prepared to enter the working world.
Student Beth who has interned with KET as their environmental champion has been looking at the importance of insects and got practical by building KentCOG’s first insect hotel.
The importance of insects and providing them with a home Every insect plays a role in the ecosystem in which it is found. The essential act of pollination is most commonly carried out by bees and butterflies; however, some ants, flies, beetles and even wasps contribute. When an insect lands on a flower, some pollen is transferred onto its body from the stamen (the male part of the flower). This pollen is rubbed off onto a different flower of the same species, where it can fertilise the stigma (the female part) to produce seeds. Some plants are capable of self-pollinating or being pollinated by seeds in the wind, however, a majority cross-pollinate as described. Therefore, the continuation of most plant species is dependent on these insects. Not only is this important for wildlife habitats, but also for humans, who rely on effective pollination for food. Due to habitat loss, insecticides and climate change, bee and butterfly numbers have been declining for years. It is therefore important for humans to aim to reduce the damage – one way of doing this is by providing areas where they can lay their eggs.
From a gardener’s perspective, pollination is necessary, but so is pest control. If a gardener wishes to be mindful of bees and other wildlife, as well as health concerns, they may be averse to using pesticides. Fortunately, there are various bugs which feed on unwanted insects and these can be purchased or encouraged into your garden by introducing their preferred breeding environments. The larvae of lacewings are well-known to devour aphids, also known as greenfly or blackfly. Aphids are one of the most destructive pests in gardens, as they weaken plants by sucking their sap, feed on their leaves, can transport plant viruses and cause the growth of sooty moulds. Insecticides are often ineffective at removing aphids anyway, but in addition to lacewing larvae, ladybirds and crab spiders eat and so control aphids. Ladybird larvae and adults also feed on other pests such as mealybugs, mites, thrips and scale insects. Minute pirate bugs, syrphid flies (hoverflies) and damsel bugs all contribute to pest removal as well.
The larger ground beetle feeds on larger pests such as slugs and cutworms as well as insect eggs. Each of these useful creatures has a preferred environment to breed and live in. So, a diverse range of bugs in a garden can facilitate the growth and maintenance of plants. In the case of food-yielding plants, this can mean a larger production of fruits and vegetables. KentCOG would benefit from this, as more produce can be sold to raise money, or more garden participants can benefit from their efforts by taking home food. An ‘insect hotel’ can encourage these beneficial bugs by containing different environments which provide them with a home and breeding-ground. This may be especially useful in the colder months when insects search for a warm and dry place to burrow or hibernate.
Materials and insect preferences Materials for a hotel can be collected from nature or be recycled items. When arranged properly, they can provide the perfect home for specific insects. • Bark attracts centipedes, beetles and spiders in addition to woodlice and millipedes which contribute to the system of recycling in a garden. • Broken plants pots and bricks and drainpipes can add to the structure and provide more space for burrowing. • Dead and rotting wood provides a home for beetles, centipedes, woodlice and fungi. • Hollow stems, bamboo and holes in wood make a great environment for solitary bees to lay eggs on the sun-catching side. • Pinecones give refuge to ladybirds and lacewings. • Straw, dried grass and dry leaf litter give ladybirds a place to hibernate over winter as well as other insects a place to burrow. • Wood chippings or rolled cardboard inside a plastic bottle provides an ideal home for pest-eating lacewings. • Hedgehog boxes and stones and tiles for frogs and newts can be added if you want to attract even more wildlife. These larger animals eat slugs and other pests in the garden.
Tips for building an insect hotel
Find a site that is level and firm, ideally in a shady area as most insects like moist and cool conditions. If you wish to attract solitary bees, ensure at least one side will receive plenty of sunlight (facing north or south).
Create a solid base from old wooden pallets or spare wood. Stack up the wood into layers with lace larger pieces at the bottom and secure each level with string, wire, or nails. Make sure that the structure has a solid back to keep in warmth and keep out moisture.
Fill each layer with the previously mentioned materials. These can be found around your garden, be donated or recycled from your house. For safety reasons, don’t make the structure more than a metre high.
Give your hotel a roof using old tiles or planks. You can cover them with roofing felt to keep it relatively dry. The roof can also be a habitat; put some rubble or soil on top which may allow wildflower growth or add some more dead wood to weight it all down.
Insect hotels can be built at any time of year, but autumn is ideal as it will provide the insects with a place to hibernate during winter.
Surrounding your hotel nectar-rich flowers will attract insects and pollinators such as bees. Planting native species (wildflowers) may attract rarer native species of bees as they have evolved together. Different bees are active throughout different times of the year, so having flowering plants throughout, ensures bees will have food all year round. Great examples are lavender (summer), honeysuckle (autumn), ivy (winter) and bluebell (spring).
My project The idea to build an insect hotel during my placement came from research that I had carried out beforehand. When I arrived at KentCOG, I saw lots of materials that had the potential to be recycled to create the environmentally friendly project. Just after the entrance to the garden, there is a large pile of relatively healthy scrap wood. I saw two structures that resembled wooden pallets as well as four draw-like boxes which would be perfect for assembling the base and structure. After checking that there would be a substantial amount of materials around the garden to fill the hotel and correct tools to build it, I began construction.
On the first day, I lead two volunteers, Hannah and Matt, and we created a base for the hotel. We sawed 4 small pieces of wood and nailed them into the corners of the first ‘pallet’. This provided balance for the second ‘pallet’ that we nailed on top. The nails that we used were largely rusty and old and so unusable for larger projects, however, they worked great for the hotel, which created another means of recycling through them. Mirelle showed us a shady, concealed spot to place the hotel and we used spades to level out the ground. We then installed the base onto the clear spot.
As there were no volunteers available on the second day, I worked mostly by myself. I began by collecting rotting wood from a large container in the garden, which contained old, disused blocks, logs and tree cuttings. I also found some fresh tree branch cuttings. I organised these pieces of wood into the base as they are the heaviest components and will help to steady the structure. Using long, thin planks of wood found on the scrap wood pile, I made a steadying platform for the second layer, on top of the base. Gemma helped me to hammer out two sides of the boxes from the woodpile, so that there would be an opening at the front and access to the middle. Once I had secured the boxes with discarded string and nails, I began searching for materials to fill them with.
Some volunteers had recently cut and collected small branches and twigs from the trees surrounding the garden, so I asked them to leave them out for me to use. When I was sure that they were dry, I placed them into the centre space of the layer. The grass had also been cut within the past week and it was very sunny, so it had dried out and become like hay. I gathered some of it and put in the back two areas of the boxes. Lots of bark was laying around in the garden, so I picked up enough to fill another space in the layer. The last area in this layer contains three different components. I found some disused bamboo sticks in a polytunnel and so I sawed and broke these up to fit in the box. Next to these is a plastic bottle which a volunteer had used the day before. I saved it, dried it out and filled it with wood chippings found in the rotting wood pile. The last items in the box were found in the tool shed. They are old, plastic tube coverings for tree saplings, which had not been needed for a long time. I broke these up to fit and filled the back-facing ends with more grass-cuttings. To fill the empty space at the back of this section, I used some of the smaller material in twig collection pile.
Another two thin planks gave a platform for the next layer of boxes. Some bush-craft days had been run in the open space adjacent to the garden and consequently, there were a few piles of leaf litter. I collected some of it into a box with all four sides intact, to give some extra shelter and warmth. The last box contains five more of the plastic tree coverings, again with grass cuttings in the ends. Empty spaces were also filled with the cuttings, which helped to keep the tubes in place. The back of the boxes and fence behind the hotel keep it relatively enclosed and will provide adequate shelter. Finally, I discovered a board with one laminate side in the scrap wood pile. This was perfect for a roof, as it was the correct size and will provide some rain protection. I placed this on the top layer and weighed it down with semi-rotting logs that I found all around the garden. My final step was to place the large log right in front of the hotel, to steady the ground, as it was on a slight mound. It could also provide a seat for anyone wanting to have a look at the creatures living inside. I cleared out some of the prickly plants and loose grass in the surrounding area, to accommodate any visitors.
Blog post by one of our volunteer, a MSc student here at the University of Kent.
I stumbled across the Kent Community Oasis Garden on a walk to the Blean from campus. It was off hours, but after a poke around I got the feeling that it was a positive space. I made note of the hours and was on my way. Finding Canterbury my home away from home and in a milder climate than I am used to getting dirty through the winter sounded like great therapy and right up my alley. It wasn’t till a few weeks later when I needed a location to conduct a micro research project for a methods course did I realize that the garden would be a perfect spot. Studying ethnobotany at Kent, the relationship members had with the physical and social landscape I felt would be an interesting study. If I was drawn in by the potential for positive wellbeing the garden offered, would anyone else? What would those other relationships look like? Does the garden positively impact wellbeing and can the how’s be identified and maybe even quantified? I volunteered weekly to find out. In all kinds of English weather, and luckily not too much rain I helped where I could, observed and interviewed members over six weeks this fall. Among the language and gardening insight was the conclusion that the members of the community take part in a reciprocal, therapeutic landscape contributing to the wellbeing of both the land and the people.
