I tried to translate it. It's not perfect, but I failed to find something else.

(Pushcha is a virgin forest)

Lyrics: Nikolay Dobronravov

The marvellous song, the marvellous place.

Light of crystal-clear dawn, light that rises world-wide.

I can understand your ages-long grief,

Belovezhskaya Pushcha, Belovezhskaya Pushcha.

Here is family home, long-forgotten by us.

Having heard the calling of ancestors of ours,

Like a grey little bird, from far-away times,

I am flying to you, Belovezhskaya Pushcha.

(twice)

Solid build of many-year-old oaks.

Baby-lily in the shade guarding somebody's traesure...

Children of your bisons don't want to die out,

Belovezhskaya Pushcha, Belovezhskaya Pushcha.

(twice)

By a secret pathway I'm making to a spring,

Where grass is so high, where bushes are thicker.

Like a dear I kneel to drink waters of yours,

Sacred spring of the truth, Belovezhskaya Pushcha.

Near birch-trees I stood where I healed whole my heart,

I will take it with me to console all the living

Your sacred song, your marvellous song,

Belovezhskaya Pushcha, Belovezhskaya Pushcha.

(twice)
