Judaism offers a long-standing and thoughtful framework for nature conservation, one that feels aligned with our work at the Wildlife Trusts, whether that’s practical conservation or community outreach. Rather than viewing the natural world as an endless resource, Jewish teachings emphasise regeneration and humility. Here are two ideas that demonstrate this.

Shmita

The concept of shmita, the sabbatical year, dates back over 3000 years. The book of Exodus states:

"You may plant your land for six years and gather its crops. But during the seventh year, you must leave it alone and withdraw from it. The needy among you will then be able to eat just as you do, and whatever is left over can be eaten by wild animals.”

Every seventh year, agricultural land is meant to lie fallow and fields are not planted or intensively worked. The Torah is recognising the land as a living entity that requires its own Sabbath; just as the human body requires a day to rejuvenate (each Saturday in Judaism), the soil requires a period of rest to prevent depletion.

This all sounds rather familiar! For us, shmita resonates strongly with the principles of nature-friendly farming, perhaps the inspiration for the ‘rest year’ as one of the key notions of modern-day regenerative agriculture.

Although developed in a very different historical context, millennia before knowledge of mycorrhizal networks or environmental stewardship schemes, shmita reflects the same understanding: long-term ecological health depends on periods of recovery, reduced pressure and respect for natural rhythms.

Tu B’Shvat

Tu B’Shvat – the New Year for the Trees – provides Judaism with a widely celebrated link to nature conservation. Originally a technical date used to calculate the age of fruit trees, the festival has evolved into a symbolic and practical celebration of trees, habitats and environmental responsibility. It has become a focal point for Jewish engagement with conservation, climate awareness and habitat protection. It is basically a Jewish “Earth Day”!

Trees occupy a central place in Jewish thought, often representing continuity, resilience and interdependence. Tu B’Shvat invites communities to actively honour these values. Many communities also reflect on the state of local environments, recognising that conservation is not only a global issue but a local one. The day is often celebrated by eating fruit and nuts, supporting nature conservation projects and holding eco-conscious gatherings. In late winter, as sap begins to rise out of sight behind the trees’ bark, this is a festival of celebration, hope and a call to action.

The Hebrew calendar is roughly aligned with the solar calendar, so Jewish festivals always fall around the same time of year. In 2026, Tu B’Shvat falls on 2nd February (the 15^th of the Hebrew month of Shvat). It is a great opportunity to engage with your local Synagogue or Jewish community.

Happy birthday trees – and happy Tu B’Shvat!
