What is the Senedd?

Put simply, the Senedd is Wales’s parliament, based in Cardiff Bay. It was previously known as the National Assembly for Wales. It’s where decisions are made that shape daily life across the nation.

That includes things like:

• How we protect nature and wildlife
• What we do about climate change
• How farming and land are managed
• Preventing pollution
• What gets built (and where)
• Public health and education 

So, when we talk about restoring nature, improving water quality, or supporting nature-friendly farming, this is where many of those decisions happen.

2026: a big shake-up

The 2026 election isn’t just another cycle; it’s a bit of a reset moment for Welsh politics. A few big changes are coming in all at once. 

The number of Members of the Senedd is increasing from 60 to 96, meaning more people representing communities across Wales.

At the same time, the map is being redrawn. Instead of the old system of constituencies and regions, Wales will now be split into 16 larger constituencies, each electing 6 Members.

And then there’s the voting system. This is probably the biggest shift. We’re moving to a proportional system where you can vote for a political party or an independent candidate, and seats are allocated based on the share of the vote they receive in each area. In theory, that should mean the final result better reflects how people across Wales actually vote.

Want nature to be a priority? Voting matters

It might sound obvious, but one of the most powerful things you can do for nature is vote.

If you are 16 or over, live in Wales, and are a UK, Irish, or qualifying Commonwealth citizen, you can take part. If you are unsure about the details, the Electoral Commission has clear guidance.

Here are the key dates to keep in mind:

• Register to vote by: 20 April 2026
• Apply for a postal vote by: 21 April 2026
• Election Day: 7 May 2026 

Registering is quick and straightforward, and it is one of the simplest ways to make your voice heard. It is also worth encouraging others to do the same, as small actions like this really do add up.

More ways to speak up for nature

Voting is just one part of the picture. Elections are also a chance to raise your voice in other ways. 

These conversations genuinely make a difference, especially during an election when politicians are paying close attention to what people care about.

The bottom line

The next Senedd will make decisions that shape the future of nature in Wales for years to come. From restoring biodiversity, reducing flooding, to supporting farmers and tackling climate change, it all runs through the Senedd.

So, if you want to see a more biodiverse, healthier Wales, this is your moment to get involved. Because nature needs a political voice, and in 2026, that voice can be yours.
