Soft toy ladybird, available from RSPB shops, price £6.99I've had an influx of ladybirds and an enormous wasp exploring our house this week. In the garden, the daffs have unfurled their petals and leaves are forming on the trees. Spring has arrived.

That means lazy days in the sunshine can't be far behind and to help inspire you, what better place to be than at the British Leisure Show at Windsor Racecourse this weekend? You'll find our trailer and marquee in the Outdoor & Country section.

We did ask, but sadly our president Kate Humble won't be dropping by. She stopped off in our office before chairing an event at Westminster, where some of our young RSPB Phoenix members got to quiz MP's on their policies on the environment. Phoenix members are the generation that will have to pick-up whatever natural inheritance we pass on.

The fact that they got to grill MP's is important as we head towards an election. Some of them may be too young to vote yet, but they have a right to know what's being done to address climate change or the quality of the water, air and soil they'll need to survive beyond our lifetimes.

The RSPB's campaign, Letter to the Future, is our generation's gift to them. It calls for all investment, by government, individuals and business, to give value for money by ensuring nature benefits.

For my part, I'm planning to invest in some garden improvements to grow fruit and veg, but I've included spaces for wildlife too, such as a new hedge that will protect my crops by acting as a windbreak, while also providing food and shelter for bugs and birds. It's not complicated. Improving insulation in homes should automatically include protecting nest sites for birds, such as house sparrows and swifts. Investing in new sources of energy or transport improvements must also include benefits for wildlife.

Kate Humble asked everyone in the office what biodiversity means. We agreed that biodiversity is the world's engine that keeps everything moving, just as long as we maintain the engine and feed it the right fuel. Then again, it just might be a big wasp buzzing round your kitchen.
