Grassy Fields to Flower Meadows

This week we found ourselves strolling along Walmer seafront while the Walmer RNLI lifeboat crew were having their regular Sunday morning training session.

Walmer lifeboat station was established in 1856 and, since then, has saved over 1,220 lives and received 28 awards for gallantry. They currently have two boats and this is the larger B class Atlantic 85 which has to be ferried across the wide shingle beach and down to the water by a tractor
They also have the much smaller D class boat that is housed in a hut on the beach but also needs its own tractor and trailer to reach the sea

We got chatting to some of the volunteers at the station and discovered that the bigger boat, called the ‘Hounslow Branch’, is new and only arrived in March this year. It was funded by Lorna Newman who lived in Hounslow and left her entire estate to the RNLI, which was used to buy the £330,000 boat. Additionally, the specialist blue tractor cost about half a million pounds, the trailer about £130,000 and the small D class boat around £110,000. When you consider that there are 238 RNLI stations around the UK, it’s clear that this charity has really huge capital costs. Yet over 90% of their funding comes from donations with only 1% coming from Government sources.

In the autumn the meadows have their annual cut and the arisings are taken away. In this way the soil will slowly be losing its nutrients, which will favour flowering plants over the bullying grasses. Little by little the land is emerging as invertebrate-diverse flower meadows rather than grassy fields. This slow process is enhanced, in a small way, every September when we buy some native flower seed from Emorsgate Seeds.

This year’s selection from Emorsgate Seeds

We choose a particularly grassy section and spread their EM6F seed mix on it, consisting of various native perennial flowers suited for calcareous soils. This is to inject the grassland with flowering plants that will then spread their own seeds next year and thus continue on into the future.

This is the area that has received the EM6F treatment this year. Dave has scalped it as much as he can with the tractor and I have scratched it over with a rake to break up the soil a bit before sowing the seed

As well as the EM6F mix, we always buy some other seeds to enjoy experimenting with. The ideal would be to have flowers constantly available during the summer that can feed both short and long-tongued invertebrates.

This year we bought 10g of bladder campion seed. The nectar in these flowers is produced right at the back of the bladder and can only be accessed by long-tongued moths and bees. Photo from Wiki commons by Krzysztof Golik under CCA-SA 4.0 International

There are always a few bladder campion plants growing in the meadows every year but we would like to encourage more. The plant releases its fragrance, nectar and pollen in the evening to lure long-tongued moths to reach into the flower for the nectar and thereby pollinate it. Long-tongued bees will then mop up any remaining nectar during daylight hours. Kent is a hotspot for rare long-tongued bees such as the shrill carder bee and the ruderal bumblebee and it would be wonderful if we could support a population of these here.

The bladder campion is being sown in three concentrated small areas like this one that has been prepared above. I can then easily visit these areas in the dark with a torch and see what is going on

Another plant with a very long flower tube is honeysuckle. There are a few honeysuckle plants scrambling through the hedgerows already, but I have now also planted a wall of native honeysuckle against the east face of a shed. This is a shade-loving plant that also releases its fragrance in the evening to attract long-tongued moths.

Because we think this shed is standing where there was once a slit trench looking out to sea in the Second World War, I ran the metal detector over the ground once I had dug the holes. However, all I found was a rusty nail which wasn’t particularly exciting.
Putting the honeysuckle all together like this will again make it easier for me to see if the experiment is working and the flowers are being visited by long-tongued moths and bees

As I worked, I was being closely observed by a couple of robins and this little dunnock, all interested in any soil invertebrates that might have been exposed by the digging .

The beautiful ringed kestrel has been hunting in the meadows every day:

And as usual the magpies are doing what they can to drive her off:

She frequently takes a bath:

And this is what she looks like immediately afterwards:

If she can hunt from a perch rather than having to hover, she will use less energy and will therefore need to find less food to stay alive:

Here she is with a vole:

And with a mouse:

The buzzard is also still around:

And tawny owls are hunting at night:

One of the magpies has caught itself a green cricket:

I don’t know what prey this fox has in its mouth, but its quite big and looks like a mammal:

The foxes have now removed all the low hanging fruit from the pear tree:

If they are going to climb up into the tree to get the few remaining pears higher up, it will be in the next couple of nights.

The moth of the week this time is the olive tree pearl, Palpita vitrealis, which turned up in the trap. This is a moth of southern Europe where its larvae feed on olive trees and jasmine. It is a scarce but regular immigrant here but cannot survive our winters. The wings are beautifully translucent with a slight sheen

I did get lots of interesting moths in the trap this week. I start going through the trap just as it gets light – usually still in my pyjamas, I’m afraid. But this week I was kept company by a pair of large leopard slugs. One slug was in hot pursuit of the other as they travelled all over the place.

I presume that this was a prelude to mating.

After nearly two hours of this, it was starting to get hot and the slugs retreated to hide themselves somewhere shady for the rest of the day

The mating of leopard slugs is the stuff of legends and how I would love to see it one day. The courtship behaviour goes on for hours and then both slugs climb into a tree or other high area and lower themselves down, entwined together, on a thick string of mucus. Their blue, translucent mating organs then come out of their bodies and dangle below their bodies, connecting together while they exchange sperm. Both participants will later lay hundreds of eggs.

I am really kicking myself for not going out with a torch and camera that evening to try to see this behaviour.

One chilly morning we noticed that male ivy bees were roosting all over the place, on leaves and ivy heads, waiting for warmth from the sun before they got moving:

The female bees can stay in their nest tunnels when the temperature drops, but the males have nowhere to go. If you look at the hind leg of this male, you can see that he doesn’t have the long yellow pollen-collecting hairs because he has no nest to provision
In comparison, this female from last week does have the hairs on her hind leg to collect ivy pollen

Over in the wood, an unusual mammal has paid a visit:

Unfortunately the photo is not good enough to tell whether this is a polecat, a polecat/ferret hybrid or simply a feral ferret. But, whatever it is, it is after the rabbits

There was another infrequently-seen mammal in one of the dormouse boxes as well:

We found fourteen dormice in September’s tour round the thirty dormouse nest boxes in our wood. This included a family of a mother and four babies whose eyes had just recently opened:

In a post earlier this month I was wondering why the spots on a giraffe can be so variable between animals:

Giraffes I photographed at Wingham Wildlife Park earlier in September with very different spots

I am delighted to say that Joe, a reader of the blog, has been able to explain this to me. There are several species and sub-species of giraffe that are found in different areas of Africa, each having identifiably distinctive spots as shown by this diagram:

I will now never be able to see a giraffe again without trying to work out where it is from!

  1. The thought of one leopard slug in “hot pursuit” of another brought a smile to my face. Sex is a powerful driver!

    And many thanks for the info on giraffes. I too had been puzzled by the sub-species, but now I can better understand the geographical context.

    1. I have never seen a giraffe in the wild and don’t suppose I ever will since we no longer fly. But they are certainly mesmerising animals to watch at a wildlife park and very satisfying to understand a bit more about them, that’s for sure.
