There may be a misprint in the defn.
Fine area of sand dunes surrounded by desert. (7) {starts with a letter near the end of the alphabet}

Tense Tories working with Austria for base (6) {starts with A or B}

Wizards are enthralled by noisy birds (6) {starts with a letter between E and L}

[Spoffy]

ERG (area of sand dunes) in WILD (desert, 'a wilderness or desert') = WERGILD (fine)

Anagram of TORIES with A (Austria) for E (base [of natural logarithms]) = AORIST (tense)

A (are) in GUANS (noisy birds) = GUANAS (lizards, misprinted as wizards)
